Every single Python project you stated simply proves my point. They are Python compilers of some sort. TXR, on the other hand, is a data processing language implemented in its own lisp which is implemented in C. In other words, TXR is an application of lisp, not just a compiler or interpreter like those Python projects you listed. So, all your examples are irrelevant.
TXR didn't need its own dialect of lisp. So, the question remains: why didn't Kaz use SBCL or CLISP? They're good enough for c.l.l. kooks like him to recommend to everyone else, but why're they not good enough for him to use?
