Line 16 is this one:

  return %same == 1 ? 1 : 0;

Prior to Perl 5.25, a non-empty hash in scalar context returned a STRING containing used and allocated buckets, separated by a slash. After that, a hash in scalar context returns the number of keys in the hash. Obviously, you did not consider that. keys %same would always return the number of keys.

And while we are at it, let's see what happens once you leave the 8 bit world and process Unicode strings. Adding the following line to the "TESTING FALSE" lines:

  hasSameChars("ABC\x{ABCD}", "ABC\x{CDEF}")                   == 0 or
+ $ERRORS++;

Yes, it seems that it does not terminate. Actually, it would terminate, after issuing many, many warnings. Much more than I'm willing watch scrolling across my screen.

Line 14 is this line:

    "@count"

Let's change my change to use "ABC\x{101}" and "ABC\x{102}" to see what happens:

Well, it seems you don't know Unicode at all, or you just completely ignored it.

Both is sad.
