I cannot agree with the above sentiment strongly enough.

There is no “golden ticket,” except in Willy Wonka movies.   There is no magic skill that you can learn, such that if you possess it, the world will beat a pathway to your door.   However, if you possess good software engineering skills, such as the ones JavaFan has cited, then you will never be hungry for work.

Savvy employers have learned not to plop “language skills” onto their job requisitions, because these keywords generate a tremendous amount of “resumé spam.”   (Yes, there is such a thing!)   Web-connected recruiters in three countries will brain-dump every sheet from everyone in their database into your in-basket overnight.   Perl is used everywhere.   You don’t have to ask.

Experienced programmers wield the tools of their trade with both competency and sound judgment.   The latter is far more important than the first.   They don’t walk around with an encyclopedia in their heads ... but they know how to use one, and when they do, they know what to look for.   It is actually quite commonplace to be presented with a requirement that you have never had to deal with before, and to be obliged to select, and then learn, an appropriate tool or package with which to address it.   (And if you ever wondered what PerlMonks is for, now you know.   It is a place where highly-competent peer review can happen in a matter of hours, or minutes.)
