I was iterating over a hash: 

while (my ($key,$val) = each(%some::very::long::named::module::foo)){
   if(testconditions($key)){
      some::very::long::named::module::drawSomethingPretty($val)}}

%foo has 56 keys, but the loop starts over again after the 3rd iteration. OK, code somewhere down in drawSomethingPretty must be performing a keys %foo and resetting my iteration. I started to rewrite as 
my($val);
foreach my $key (keys %some::very::long::named::module::foo){
  $val = $some::very::long::named::module::foo{$key};
  if(testconditions($key)){
      some::very::long::named::module::drawSomethingPretty($val)}}

but I didn't like how it looked. Is there a succinct yet readable way still use each, but not be vulnerable to being reset?
