that would give something like this?

import std.stdio;

void main()
{
	char[] s = "hello";
	// += for advancing an iterator, why not ++?
	for (iterator i = s.begin; i != s.end; i += 1)
		writefln(s[i]);

	// ??? i is an iterator or a char  ???
	foreach(i; s)
		// extend writefln to take iterators ?
		// but that would mean that it must be possible
		// to determine a value from an iterator
		writefln(i);
}
