Some Prolog systems do (the tokeniser in my book offered it, IIRC).
One of the people on the Prolog standard mailing list has been jumping
up and down in anger because SWI Prolog has it. But when you have
characters like 0'x, 0'y, 0' , it's really nice to have 0\s. (Don't
laugh. Erlang's $x, $y, $ , is just as bad.)
I actually have a keystroke in my emacs-ish editor to remove trailing
spaces because their presence breaks things more often than it helps.
