Well, neither of those is the right result, since index is probably
not going to be returning integers in Perl 6, but string positions
which might have different integer values depending on whether you
look at them as bytes, codepoints, graphemes, etc. And the string
position value will be true for valid string positions and false/undef
otherwise.
When you call index, it's going to assume that 999 is to be converted
to a string position under the current Unicode pragma, which turns
out to be undefined on the string in question, so your call above
probably either warns or throws an exception because you tried to
use an undefined value to do something defined.
