Thanks for pointing this out - It certainly makes things much easier for me.

I must look pretty obtuse - I didn't realize it could be used this way. All the C examples in the manual are for #includes and function declarations/prototypes but never function bodies, and the manual warns that the foreign parser can only deal with a limited subset of C.  So I thought that foreign-lambda* was needed for the actual inline C function bodies. Clearly as you point out it is not, which is really nice.

I'm more impressed with Chicken every day. Thanks again for your help.
