Historically -1 has been used (on unixlikes) to mean 255; in the old days,
whether the exit status was signed or not was per platform/implementation.
(This is why shells produce 255 for command not found.)

And... well, try these in perl 5 and see what you get. (tl;dr: the same
values as rakudo)

exit -9 # exit code is 97
exit -99# exit code is 193
exit -9 # exit code is 1
exit -  # exit code is 1

I think that only non-negative numbers should be allowed.
