fine
i really don't need to see most punctuation or
capitalization to understand english sentences
the thing is that i _want_ to see it because i think it
makes the prose look better
it's like
i know there should be a question mark after this sentence,
so why not add one
it won't be distacting because not only am i used to seing
question marks --- i add missing ones mentally when i read

I compared `!= NULL' and `(not (null ...))' to punctuation.
I guess, in a way, punctuation makes prose "ineffective".

That's ridiculous. If you have to spend many brain cycles
figuring out what `node != NULL' means, I would hesitate to
say that you are fluent in common idiomatic C.
It's sort of comparable to stopping every time you see the
word `but' and noting that, in fact, it just means `and'.

Well, I guess we'll just have to agree to disagree,
because I think that's very hard to read.
I would write it as follows:
for (current = argv; *current != NULL; ++current)
process (*current);
Maybe we just speak different dialects of C or something.
I speak "verbose" and you speak "cryptic". :-)
