Why would we ever use source filters when we're going to have a
beautiful extend-syntax macro system. (I hope!) Is anybody going to
put out a macro RFC? The one I have in mind is R. Kent Dybvig's
hygenic macro system for Chez Scheme. (There's a paper floating
around here someplace. When I find it I'll post pointers to it.)
