= W =
Wrong Thing n.
A design, action, or decision that is
clearly incorrect or inappropriate. Often capitalized; always
emphasized in speech as if capitalized. The opposite of the
Right Thing; more generally, anything that is not the Right
Thing. In cases where `the good is the enemy of the best', the
merely good -- although good -- is nevertheless the Wrong
Thing. "In C, the default is for module-level declarations to be
visible everywhere, rather than just within the module. This is
clearly the Wrong Thing."
