Excellent explanation of a fun, and is more or less what I knew of
how funs work.  I think what I was going for was more to make it
easier for the developer to write the messages...

The first line is much longer to write than the second.  So I think
my comment was largely written because I found the second form to be
shorter to type.

This I didn't realize, and now that you make the point, I can see
how a fun might in fact take up less space than a tuple.  Saving a few
bytes or a few machine instructions to make it 'faster' is really not
all that important, as the X server alone must be chewing up a good
amount of resources, let alone the ex11 code.  I think I just threw
that in as another excuse for why I suggested the second form above.

What a waste of bytes this message is.  But we're not counting
bytes are we?  :-)
