/**
* A visitor that transforms all "extended AST" nodes into "atomic AST" nodes.
* Except for everything inside a quote, which is left alone.
*
* It also does double work by "flattening" begin nodes whenever possible, to allow definitions
* to be visible outside the begin structure (since begins don't have their own scope).
