| Summary : Don\'t write loops on hashes, only on keys and values of hashes
|
Description :
When \"looping over hashes,\" we mean looping over hash keys or hash values.
If you forgot to call \'keys\' or \'values\' you will accidentally loop over
both.
foreach my $foo (%hash) {...} # not ok
action() for %hash; # not ok
foreach my $foo ( keys %hash ) {...} # ok
action() for values %hash; # ok
An effort is made to detect expressions:
action() for %hash ? keys %hash : (); # ok
action() for % ? keys % : (); # ok
(Granted, the second example there doesn\'t make much sense, but I have
found a variation of it in real code.)
