wart

warm boot | = W = | washing machine

wart n.

A small, crocky feature that sticks out of an otherwise clean design. Something conspicuous for localized ugliness, especially a special-case exception to a general rule. For example, in some versions of `csh(1)`, single quotes literalize every character inside them except `!`. In ANSI C, the `??` syntax used for obtaining ASCII characters in a foreign environment is a wart. See also miswart.
