You could easily argue, that beyond the end is an error, but I agree
with the way Perl allows the start to be at the end. I think of it as
with (pseudo-) C:
char str[] = { 'A', 'B', '\0' };
substr(str, 0) == "AB"
substr(str, 2) == ""
substr(str, 3) ERROR

If things doesn't make sense, I think there should be some kind of
warning too (like with array to string cast).

True, but if you do it like Perl, it will only break BC for the case
where start is at the end of string, which is an error now.

Yes, with the case where start is beyond the end (which is an error),
there should be a warning or an error.
