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. > Or some code even? :-)) > 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.
