Why should you use Perl? Wheneven others ask this question, I always say, there is no way you can develop this faster in
other languages than do it in Perl.
I think you need to clarify that point a little. There may be no way you
can develop this faster in other languages, but there are several other
languages that would allow for equal ease of development: Ruby and Python
for sure (but also Lua, Icon, and Lisp are good candidates). Don't confuse:
"Best tool for the job" with "Best tool for your mind".
There is absolutely nothing wrong with the latter justification when
selecting among a set of relatively equally capable tools, but it is
incorrect to equate this with some superiority of the chosen tool.
