Sorry, I think my post may have been excessively specific; I've edited it to say "writing a new Python interpreter/compiler/runtime" instead of just "writing a new Python interpreter". I was trying to make a generic point, not one specifically about a Python interpreter. (At least, if I'm interpreting your reply correctly.)

I mean, you can get something out of transpilers--not typically maintainable code.
Of course, if it started out as a "this seems like a cool project", that skews the "a is more efficient than b" ratio significantly.
