Way more than half, in my opinion. I don't see those features used
nearly as much as they could be in contributed code.

Yes! Clarity counts, especially six months or five years from now,
when you have to maintain your code. (I still maintain business
programs I wrote 12 years ago - sometimes it's hard to remember
just what a piece of code is supposed to do) Every little bit helps.

The ^ is generally understood to stand for power, and it's not being
used for anything else, is it?
I don't understand the problem with zero - based vs 1 - based indexing,
unless you're trying to use basic code without re-writing. Why would
there be any reason to continually adjust the index s[x-1] ?
What's wrong with calling the first item [1] and the second item [2]...etc.?
Re: Procedures/Functions
I suppose we could replace *procedure foo()* with *void function foo()*,
but where's the gain? The way it is, we don't have to look up each call
to see if it returns anything, and we can't call a function without
actually doing something with the result (kinda important).
One thing that might lead to shorter, clearer code would be to allow
var parameter passing to procedures.
Turbo Pascal allows this, and I use it maybe 10% of the time. Most
of the time, it is because Pascal functions can only return 1 result,
and I need several, so I use a procedure (var a,b,c) instead. Other
times it is because the call is more readable than a function assignment
would be.
Enough...
