Guile is LGPL anyway.) A Guile linked into Emacs would of course inherit the GPL of Emacs. I don't see its standard dll-loader magically making any loaded module become part of "software as a whole" with regard to licensing unless it specifically called Emacs functions. But as long as the module would also work with a standalone GUILE interpreter, I don't see the GPL gaining traction on it. But of course a tight coupling between Emacs and GUILE _will_ make it more attractive to write modules with components tieing into editing. --=20 David Kastrup
