I've added the following function to std.conv:

Target parse(Target, Source)(ref Source s, uint radix)

Check the unittest:

unittest
{
    foreach (i; 2..36) {
        assert(parse!int("0",i) == 0);
        assert(parse!int("1",i) == 1);
        assert(parse!byte("10",i) == i);
    }
    assert(parse!int("0011001101101",2) == 0b0011001101101);
    assert(parse!int("765",8) == 0765);
    assert(parse!int("fCDe",16) == 0xfcde);
}

The unittest passes, were it not for bug 4309. (The "ref" in "ref Source"
apparently changes the pointer to the string literal.)
