That's nasty. warnings::register is a shortcut for the common case of
packages registering their own category; it's just obfuscatory to go
through it to register an unrelated package's category.

This is what I envisioned, and I think it's the pattern to favour.
It's nice and clear, with the registration explicit and distinct from
the bitset toggling.

Strikes me as confusing. What does it do to the Hash::Util category,
exactly? Register it, yes, but also operate on its lexical enablement?
More a problem with "use warnings REGISTER => ...", but it's unclear
in any case. Also, the FATAL/NONFATAL directives are confusing enough,
and this would introduce combinations of the directives.
Registering someone else's warning category is an unusual requirement.
It doesn't need to be especially succinct.
