CLISP, a GPL'ed Common Lisp byte-code based system, is GPL'ed, with
the additional note that use of the standard language interface (as
specified in the ANSI standard) will not be considered "linking", but
using non-standard CLISP extensions is considered "linking" for the
purposes of the GPL.  This means that embedding CLISP in a C program,
using the foreign function interface, etc., require that the program
be GPL'ed, while writing portable code does not.  If one wanted any
looser a definition of "linking" I don't see any advantage over using
the LGPL.  Personally, I think that the LGPL is the way to go for
something like this, which really is similar in quality to the C library.
