I disagree there pretty heavily. There are a lot of C variants over there: Objective-C, C++, Pro*C, etc. (There are a lot of software projects that actually include a specific C pre-processor of some kind, check, eg. the C sources of emacs lisp, of GNU clisp, etc). As soon as you write a new front-end to C, you get a C variant, just like as soon as you write a DSL in Lisp you get a Lisp variant (and vice-versa). The C world is a Tower of Babel. Now, it's true that it's easier to do in lisp than in C, since in C the tools are external (you have to use flex/bison to implement the pre-processor) while in Lisp the tools are internal, and you just need to write a single defmacro to introduce your variant.
