You'd probably lose. Its everywhere.

Catalyst is where its at. And if you need a one-off framework, CGI::Application is easy as pie.
Coupled with the CPAN, the ecology of other languages look pretty useless to me.
There are a lot of people using perl. I've been introduced to new several new industries lately, and perl lets me develop apps that would need a team of HPCs and millions of dollars to do. And the new projects and requests keep on queuing up.
To me the biggest reason people don't hear much about perl is because its proponents and users are too busy getting stuff done.
