The -P Convention

Turning a word into a question by appending the syllable P ; from the LISP convention of appending the letter P to denote a predicate (a boolean-valued function). The question should expect a yes/no answer, though it needn't. (See T and NIL.)

At any time:

A: (Humorous) Yes, the world has a state.

On the phone to Florida:
Q: State-p Florida?
A: Been reading JARGON.TXT again, eh?
