That is really neat - I'd assumed -bareword was just a convention and that => was responsible for the quoting. Is there a reason that - and => aren't mentioned in the "Quotes and Quote-like Operators" section of perlop?

The "Comma Operator" gets its own heading
and the minus is listed under "Symbolic Unary Operators".
