I wonder what RMS' and Eli's reaction would be. >=20 > I just gave it. On second thought, I don't think I understand the idea at all. What does it mean "a Lispy language, easy to learn"? Is it a Lisp dialect= , or is it C with a set of Lisp-like macros preprocessed into C? What exactly are the C aspects that we are trying to save the programmer =66rom? And which part(s) of the core do we expect to be able to rewrite in this "Lispy" language?
