"You unlock this door with the key of a hash. Beyond it is another dimension—a dimension of strange constructs, a dimension of improbable behaviour. You're moving into a land of both weird syntax and unlikely semantics, of unintended features and unexpected beauty. You've just crossed over into...The Twilight Perl."
Join Damian for a head-trip through a dozen or so arcane and sinister “features” of Perl. Much of what you thought was required...isn’t; some of what you thought was impossible...is easy. Cast off your strictures and warnings and set your programs free. Embrace the Dark Side of the Code. You have nothing to lose—except your sanity!
