Follow-up Comment #28, bug #67612 (group groff): [comment #27 comment #27:] > `&usage(1);` looked to me like it might be saying "throw the > usage message and exit with status 1".
Fair point. My inclination in that case would be to document the meaning of
the function's parameter once at the function definition, rather than at each
call site, but given this function is called exactly twice, that seems to make
no practical difference.

I think that misses the point: C/C++ are weakly typed, and Perl is not typed.
Adding a new variable type to a weakly typed language is a language expansion;
adding one to an untyped language is a language redesign, because there's no
framework to "add" to.
