In one exchange on comp.lang.python a few years ago, I posted a highly
un-Pythonic and generally derided tokeniser program.

However it turned out to be faster than someone else's more elegant
tokeniser based on regular expressions.

And that was despite the regular expression library being implemented (I
would presume) in compiled native code. Mine would have been mostly
byte-code.
