Well, I think the primary utility of Perl in this regard is regular
expressions (a.k.a. regex, regexp, etc.), and many programming
languages have adopted these from Perl (or at least provide toolkits
for them). Regex strings are part of native Java and PHP, and are
actual elements of ActionScript. A great number of text editors allow
search and replace by regular expression patterns, too.
Regular expressions are very useful and really *are* something that
can be learned in a relatively short amount of time. (They're not a
programming language in and of themselves, though, more like a textual
query language.) The syntax is kind of odd, but it's succinct and
powerful. Good place to start:

Didn't mean to imply otherwise.

I dunno, knowing the basics of XML, for example, can help an awful lot
for many tasks.
A good introduction: http://w3schools.com/xml/xml_whatis.asp
as prerequisites, that's not really true, at least for the "XML Basic"
