in reply to Being impervious to an 'each' reset

You could assign %some::...::module::food to another hash and iterate over that, in which case you'll be iterating over an entirely different hash. 
use Data::Dumper;

my %hash1 = ( key1 => 'hello', key2 => 'world' );
my %hash2 = %hash1;

print Dumper \%hash1;
print Dumper \%hash2;

However, the code you posted makes me uncomfortable. You seem to be tinkering with some guts that shouldn't be tinkered with.

    You could avoid copying the large hash by using a reference: 
    my $thingy_ref = \%Foo::Bar::Baz::thingy;

foreach my $key ( keys %$thingy_ref ){
    print "$key => $thingy_ref->{ $key }\n";
}

      Erm, then you'd have a reference to the same hash you're trying to avoid resetting the each iterator and the OP would be back to square one. The iterator is a property of the underlying hash, not how it's accessed.
