Right, that's the point of TFA. It doesn't list "special" operators, it lists "secret" operators -- that is, operators combined from existing sigils that do clever things.

The "Venus" operator is a good example: it's the '+' addition operator! You just add zero to a value that's coercible into a number.

The Eskimo operators are also interesting: similar to a SQL injection attack, you use a close brace and an open brace to stop and start a new code block from within a string that's sent to the interpreter. Perl didn't invent open and close braces: hence the verb "discover" rather than "implement".

The whole page is a bit of a lark, and a good example of why some of us don't enjoy Perl!

Fair point. I should've read more before jumping in here with my first reaction.
