Re: Use of .lisp Extension

As has already been pointed out, the following does magic:

   (push '#".lisp" sys::*source-file-types*)

Under Unix, renaming is not a big pain:
for f in `find . -name '*.lisp' -print`; do ln $f `basename $f .lisp`.lsp; done

Because I want CLISP to support its features across platforms, and I can't
support the .lisp extension on DOS.

This would be dangerous, since ".lis" is the extension of the listing files
produced by  (compile-file ... :listing t).
