I'm not going to use this at all. I don't see the
benefit of it because if I misspell a function, I will
realize that immediately as the keystroke or otherwise
invocation won't work. Besides I don't want to stop
and think if I should but the sharp sign there or not.
I never did and it always worked. Part of the
pleasure with Lisp is not thinking like a computer,
but like a man, and this poor man's typing is a step
away from that while not offering any benefits what
I can see. The OP presented it as something you should
definitely do but the subsequent discussion hasn't
showed that by far, and even he himself couldn't say
why you should bother.
