It just happens that Marco Maggi and me have agreed to unify our FFI
implementations in the near future; I have `(spells foreign)'[0], and he
has an FFI in his nausicaa library collection[1]. 

I hope (and kind of expect, even :-)), that the result of this effort
will be a low-level FFI in the spirit of CL's CFFI-SYS[2], with some
documentation, and working on Ikarus, Ypsilon, Larceny, Mosh and PLT
Scheme. This layer will be rather minimimal, and not very nice for doing
hand-written glue code in, but it will suffice nicely to support
sbank[3], for example. It should provide all primitives to build more
sophisticated FFI layers on top of it.

I think when we have some documentation out there, it should be
relatively straightforward to do an implementaton for Guile -- I could
very well imagine I will be tempted at some point to rip the guts out of
G-Wrap, and use them to build an implementation for Guile, just for the
heck of it :-). We'll see -- the above-mentioned unification hasn't
really begun yet, but I expect that there will be something to show by
the start of next year or so.
