... and a local $^W = $my_bits doesn't change them at runtime for scopes further down ...

What do you mean? This works fine:

use strict;

my $lasthash = {
    lastfunc => sub { last ; },
} ;

sub lastfunc {
    last ;
}

sub test {
    # local ($^W) = 1 ; # Activate this line to display the warnings
    while(1) { lastfunc } ;
    while(1) { $lasthash->{lastfunc}->(); } ;
}

test() ;
