I've thought about using this Lisp interpreter to bootstrap a compiler for a new language, probably targeting HolyC. If someone were to write some decent lexer/parser generator tools in HolyC it would go a long way in making something like that possible.

Call it Protestant.

Alternatively, HolyC++ or HolyD.

HolyMoly, duh.

Ideally a HolyC++ would be able to compile normal HolyC without any changes to the source while also adding new stuff and while not being C++ in the process. That all would be very neat.

More like unholy.
