When I see this, I think about this:

for (std::vector<int>::const_iterator i = v.begin(); i != v.end(); ++i) {
	int x = *i;
	...
}

Why is foreach (x; v) ... better than the former?

The problem is, if is hard to write, or ugly to read, people won't use it,
or will use it less. In Python tuples are easy to read and write, so
people use them everywhere and they are really useful (especially for
FP-style programming, where is more common to return multple values).

I think that library tuple *implementation* is a great idea (like library
dynamic and associative arrays implementations), but not having support in
the language for tuples is bad (like it will be not to have dynamic and
associative arrays). I think the 3 are very fundamental types and deserves
language support.
