Perldoc says pretty same for them, like

next cannot be used to exit a block which returns a value such as eval {} , sub {} , or do {} , and should not be used to exit a grep or map operation.

I read cannot as doesn't work. But. In some modules, like Par::Dist I can see code like:

File::Find::find( sub {
        next unless $File::Find::name;
        (-r && !-d) and push ( @files, substr($File::Find::name, 5) );
    } , 'blib' );

What is it? Outdated documentation? Do I get cannot wrong way? Some tricky next, like sub?

Also, TIL, missing in docs, that last/next/redo may be used in statement modifiers, like say $_ and last for 1,2,3

I'm working on new code inspection, so question is not rythorical.
