1.5. Operators

As we alluded to earlier, Perl is also a mathematical language. This is true at several levels, from low-level bitwise logical operations, up through number and set manipulation, on up to larger predicates and abstractions of various sorts. And as we all know from studying math in school, mathematicians love strange symbols. What's worse, computer scientists have come up with their own versions of these strange symbols. Perl has a number of these strange symbols too, but take heart, most are borrowed directly from C, FORTRAN, sed (1) or awk (1), so they'll at least be familiar to users of those languages.

The rest of you can take comfort in knowing that, by learning all these strange symbols in Perl, you've given yourself a head start on all those other strange languages.
