Getting three times the calls for Perl than you get for C++ could be less of a reflection of Perl's popularity as it is of a lack of Perl programmers in comparison to C++ programmers. While prospective clients may find someone else for C++, perhaps they have far fewer options when they need Perl work done. Then again, I'm not you, and I wouldn't know.

The benefits of programming Perl are many, the drawbacks few. A good solution for a vast range of problems.
