Excellent suggestions. I hadn't figured out how to make the colon syntax work
with non-argument variables.

I don't either. Somebody argued a big savings and I explained why don't see
it.

I think you make a good point.
I suppose my experience is analagous to some of the Pythonites who say "I
simply don't make THOSE kind of errors." I have used C and C++ for so long
that I generally don't make pointer errors or malloc errors -- the kind that
can take a long time to fix. Generally, in C++ I too generally am only
debugging the "logic" errors.
But given your average college graduate or a person who's only used C for a
few years -- yeah, your point is quite valid. Since they aren't properly
disciplined to avoid the problems, they spend more time fighting them. And
Java's or Python's garbage collection would be a big win.
Hell, I've already said GC is probably Python's biggest win even for me.
