Kage has asked for the wisdom of the Perl Monks concerning the following question:

Lately, I've been messing with the $^O and $^W perl expressions, and I've found that there are dozens of others.

I tried a CPAN search, a Perldoc search, and just about every other site, but not one single site has a list on the $^ expressions. My question is, what are they (called), and where do I find a list?

    Try perlvar in the perldoc.

    Update: There is also a section of Special Names in the Camel Book (and I assume the Perl Reference Book has it also).
