[plt-scheme] getting a parse tree with bindings info

A lot of the Scheme programming tools I want to write need to work
directly with the source code, but using the variable bindings and
syntax extension information that is resolved by syncheck.ss.

I suspect I want a parse tree that's annotated with bindings resolution
and source position information.

Should I just clone the syncheck.ss code and adapt it?  Or is there
already an easier way to get at the information?
