My main concern is actually with 'semantics' (if that's the right word.) I.e.,
the term #while seems to be quite logical and understandable in its meaning:
"while (this is true) do this stuff" etc. Same thing with #if. But--using #for
as an example again--I'm not so sure I understand what "for" signifies, in an
English syntax sense. (Actually, I do seem to recall 'for-next' being a part of
Fortran IV that I learned long ago in college. I think. Which has been my only
experience with 'real' computer programming, aside from Basic or one of its
iterations on an old Commodore computer. But #for doesn't immediately create a
mental picture of what it does.) So my own desire would be to have SDL syntax
that is as easy (or even easier) to 'quickly grasp' than the current version's.
