Hi, Sven!

Some eggs have been ported, but only for testing CHICKEN 5, you can find them

As John said, syntax-case will not be ported to C5, I think, the macro system
is interacting heavily with the module system, so hooking a separate expander
into the system is very hard and will not be fully transparent.

But if you use an expander as a separate preprocessing step for standard Scheme
code, it should be possible to use the portable syntax-case package at

Some hacking will be necessary, I'm afraid.
