Description Nick Sabalausky 2011年08月26日 11:04:43 UTC 
int[] foo(string str)
{
	int[] ret;
	foreach(i, dchar c; str)
		ret ~= i;
		
	return ret;
}
pragma(msg, foo("Hi"));
Expected: [0,1]
Actual: [1,2]
Among other likely problems, this causes stripLeft to give the wrong result at compile-time:
// Should fail, but currently passes:
static assert(stripLeft(" Hello") == "ello");

Increasing priority since this is a wrong-code sort of issue.
