I'm not sure whether it has the kinds of things you're looking for, but
the code in plt/src/mzscheme/src is all processed by xform to build
mzscheme3m.

You're right: it's very difficult to test. Unfortunately, I don't have
a better answer than "make sure you understand the issues and write
code that works".

It might make sense to post some code fragments here, especially pieces
that trip up xform or that you're unsure about.
