I think there=E2=80=99s a tension between the interest of Guile, which is to provide a convenient way to access useful features, and the interests of implementation-neutral =E2=80=9Cplatforms=E2=80=9D like Wak. For instance = I find it important to have SXML, LALR, etc. usable out-of-the-box; it lowers the barrier to entry. Besides it=E2=80=99s still unclear (to me) what the future of Wak and simil= ar projects is. I hope that it will take off, but I haven=E2=80=99t forgotten Snow, ScmPkg, etc. either. > I think the ideal solution I think there=E2=80=99s no ideal solution, not yet. :-) Thanks, Ludo=E2=80=99.
