(require scheme/foreign)

require: unknown module: scheme/foreign

does Scheme has stable FFI at all?

depends on the implementation you are using. You should consult the documentation for your implementation.

MzScheme of course. Looks like there are myriad of FFI implementation, in contrast to CL, which has single CFFI. And the standard library is bigger and less portable than CL's. Anyone who tells you, that Scheme is minimalistic, is liar.

yes. Use this one instead. http://armpit.sourceforge.net/

MzScheme
It's got one of the best FFI I've ever seen (I've heard Chicken's FFI is even better), but I'm not sure why you're still using MzScheme instead of Racket/the old libraries instead of the new ones. http://docs.racket-lang.org/foreign/index.html

Newer versions fail to install on my Linux distro and I'm just playing, to see what it can do.

python's ctypes is far more elegant

Python has no FFI at all. It require external C/C++ compiler.

chicken's is really good. it compiles down to C so it bascially uses inline functions instead of a ffi

Why do we need C/C++ at all? It's long obsolete.

It uses fucking complicated infix notation, scary as Haskell:



(_fun _double (p : (_ptr o _double)) -> (r : _double) -> (values p r))

Scheme FFI
