Can Guile reuse GPL'd code, though, since it is LGPL? We could have GPL modules, though that would be a case-by-case decision. In this case it may be a bad idea; OTOH it could be argued that the C parser is invoked only a compile-time, and thus users don=E2=80=99t have to= be GPL too, just like applications compiled with GCC don=E2=80=99t have to be = GPL. But, hmm, that=E2=80=99s tricky. ;-) > I see that Larceny is licensed under the LGPL, but the copyright is > probably not assigned to the FSF. Would reusing that be possible? Yes, if there are good reasons to do so. There are several modules in Guile with non-FSF copyright. > Just to be clear about the overall idea, what I'd like to do is to > work on new features with as many people as possible, and to duplicate > as little code as possible, because I think this would lead to more > cool things made with Scheme, which would ultimately be better for all > of us who like using the language.

That=E2=80=99s another way to share efforts w= ith others. Thanks, Ludo=E2=80=99.
