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.
