perl cannot be written in Perl

Yes it can. There is nothing from stopping you writing a bootstrap parser and eventually creating a self-compiling Perl parser+runtime written in Perl. But, and this is the 2**16 dollar question.... why would you want to do a thing like that?

(For those following along at home who can make no sense of this dialog, the language is Perl, and the interpreter that interprets said language is perl).

One thing I do know... Perl should not be used when speed is of the essence. I'm currently stress testing Regexp::Assemble. I started the run last Friday afternoon on a hexaprocessor box. The run has performed about 147 million combinations as of right now (more than 4.6 billion unit tests), a grand 7% of the problem space...

On the plus side, the run hasn't turned up any bugs.
