So, you'd have us throw away all the useful warnings

I'm not sure what other warnings pack 'C' or pack in general can emit. You could submit a patch so that pack overflow warnings are a subclass of pack warnings.

Oh sure. "Wide character" says 'overflow', like super-injunction says right to privacy for all.

It doesn't say "Wide character". 

>perl -we"$_ = pack 'C*', 257"
Character in 'C' format wrapped in pack at -e line 1.

It's saying how it handled an overflow.

Really? Can you guess where this direct quote " A Unicode character number." comes from?

That's easy, but moot. I've already pointed out the documentation is wrong. There is no such thing as Unicode number 0x20000, yet 

>perl -wE"say sprintf '%X', unpack 'U', pack 'U', 0x200000"
200000

The docs sometimes assign Unicode semantics to operations where no such semantics exist. "A Unicode character number." should simply be "A character number." In Perl, a character is a number in 0 to UVMAX.
