Actually, according to the docs: If no "unimport" method can be found the call fails with a fatal error., so this should fail:

$ perl -e '
*UNIVERSAL::import = sub { print "Whoops!" };
my $x = bless {}, 'Foo';
$x->import;
no Foo'

Except it doesn't fail. This appears to be misdocumented. If you use strict, you'll get a baredword warning, but that's still not what the docs say. Am I misreading?

Further, I think the symbol table entries should not be autovivified. If you're doing some funky work walking the symbol table, those 'faux' entries could cause bad results. I don't like it. Nosireebob. I don't.

Cheers,

Update: Added the word 'not'. Kinda changes the meaning, doncha think? :)

Update 2: I submitted a POD patch to P5P, but Abigail beat me to it.
