in reply to Undocumented variable?

The built-in variables documented in perlvar are a part of a declared typeglob. That means you can even do silly things like this:

#/usr/bin/perl use strict; use warnings; @> = qw(Roses are red. Violets are blue.); print $_, " " for @>;

@> looks like a wrapped rose to me...

    You can even make Perl program that looks like a rose with a stem. The following program compiles and runs, although it doesn't do anything useful:
    perl -e '@}-`-,-`-%-'
