Doesn't this break a lot of C and C++ code?
for (; a<b; a++) {}
is legal. I don't think that an empty statement after for is used in
"a lot of code."
it's a trivial fix and easy to find. Heck, you hardly need to think!
No, it isn't easy to find. This is in D because a colleague of mine, who
was an expert C programmer (the best in the company I was working for),
came to me with:
for (xxx; i < 10; i++);
{
... code ...
}
and said he could not figure out why his loop executed only and exactly
once. He'd fiddled with it for a whole afternoon. He said he must be
missing something obvious. I said you've got an extra ; after the ). He
smacked his head and about fell over backwards.
So it's illegal in D, along with:
if (condition);
and similar constructs. Have to use a { } to indicate a blank statement.
