 * HOF scope transform which applies given parser to result of given scope's
 * result, or if result is null, first joins children using {@link xfJoin}.
 *
 * @remarks
 * The nested parser is applied to a separate {@link ParseContext} and if
 * successful, the resulting AST will be transplanted into the current parse
 * scope. If the nested parser fails, the scope will remain untouched.
 *
 * If the current parse context retains line/column details, the inner parse
 * context will be configured to produce true absolute offsets for its results
 * as if they were in the main context.
