I agree, though the name "lambda" actually pre-dates Lisp.  It comes
from Alonzo Church's "lambda Calculous" of the 1930's.

ML uses "fn", which like "func" reads beautifully.  The construct ceases
to be arcane when people hear that "lambda x: x * 2 + 3" reads as "that
function which applied to x, returns x * 2 + 3".
