// easy to recognize.
// The `beforeExpr` property is used to disambiguate between regular
// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).
//
// The `startsExpr` property is used to check if the token ends a
// `yield` expression. It is set on all token types that either can
// directly start an expression (like a quotation mark) or can
// continue an expression (like the body of a string).
//
// `isLoop` marks a keyword as starting a loop, which is important
// to know when parsing a label, in order to allow or disallow
// continue jumps to that label.

// - Record name declarations for bindings in the appropriate scope.
// - Check duplicate argument names, if checkClashes is set.
//
// If a complex binding pattern is encountered (e.g., object and array
// destructuring), the entire pattern is recursively checked.
//
// There are three versions of checkLVal*() appropriate for different
// circumstances:
//
// - checkLValSimple() shall be used if the syntactic construct supports
// nothing other than identifiers and member expressions. Parenthesized
// expressions are also correctly handled. This is generally appropriate for
// constructs for which the spec says
//
// > It is a Syntax Error if AssignmentTargetType of [the production] is not
// > simple.
//
// It is also appropriate for checking if an identifier is valid and not
// defined elsewhere, like import declarations or function/class identifiers.
//
// Examples where this is used include:
// a += …;
// import a from '…';
// where a is the node to be checked.
//
// - checkLValPattern() shall be used if the syntactic construct supports
// anything checkLValSimple() supports, as well as object and array
// destructuring patterns. This is generally appropriate for constructs for
// which the spec says
//
// > It is a Syntax Error if [the production] is neither an ObjectLiteral nor
// > an ArrayLiteral and AssignmentTargetType of [the production] is not
// > simple.
//
// Examples where this is used include:
// (a = …);
// const a = …;
// try { … } catch (a) { … }
// where a is the node to be checked.
//
// - checkLValInnerPattern() shall be used if the syntactic construct supports
// anything checkLValPattern() supports, as well as default assignment
// patterns, rest elements, and other constructs that may appear within an
// object or array destructuring pattern.
//
// As a special case, function parameters also use checkLValInnerPattern(),
// as they also support defaults and rest constructs.
//
// These functions deliberately support both assignment and binding constructs,
// as the logic for both is exceedingly similar. If the node is the target of
// an assignment, then bindingType should be set to BIND_NONE. Otherwise, it
// should be set to the appropriate BIND_* constant, like BIND_VAR or
// BIND_LEXICAL.
//
// If the function is called with a non-BIND_NONE bindingType, then

// duplicate argument names. checkClashes is ignored if the provided construct
// is an assignment (i.e., bindingType is BIND_NONE).

// A recursive descent parser operates by defining functions for all
// syntactic elements, and recursively calling those, each function
// advancing the input stream and returning an AST node. Precedence
// of constructs (for example, the fact that `!x[1]` means `!(x[1])`
// instead of `(!x)[1]` is handled by the fact that the parser
// function that parses unary prefix operators is called first, and
// in turn calls the function that parses `[]` subscripts — that
// way, it'll receive the node for `x[1]` already parsed, and wraps
// *that* in the unary operator node.
//
// Acorn uses an [operator precedence parser][opp] to handle binary
// operator precedence, because it is much more compact than using
// the technique outlined above, which uses different, nesting
// functions to specify precedence, for all of the ten binary
// precedence levels that JavaScript defines.

/**
* Function that returns two types of paths, one relative to symlink, and one
* relative to the current working directory. Checks if path is absolute or
* relative. If the path is relative, this function checks if the path is
* relative to symlink or relative to current working directory. This is an
* initiative to find a smarter `srcpath` to supply when building symlinks.
* This allows you to determine which path to use out of one of three possible
* types of source paths. The first is an absolute path. This is detected by
* `path.isAbsolute()`. When an absolute path is provided, it is checked to
* see if it exists. If it does it's used, if not an error is returned
* (callback)/ thrown (sync). The other two options for `srcpath` are a
* relative url. By default Node's `fs.symlink` works by creating a symlink
* using `dstpath` and expects the `srcpath` to be relative to the newly
* created symlink. If you provide a `srcpath` that does not exist on the file
* system it results in a broken symlink. To minimize this, the function
* checks to see if the 'relative to symlink' source file exists, and if it
* does it will use it. If it does not, it checks if there's a file that
* exists that is relative to the current working directory, if does its used.
* This preserves the expectations of the original fs.symlink spec and adds
* the ability to pass in `relative to current working direcotry` paths.
