Re: Perl Best Practices for naming variables

[pg]

Other than use plural for collections (array/hash), it is also nice if you can name the "iterator" wisely:

for my $friend (@friends) { #the relationship between $friend and @fri
+ends are visually clear
    ...
}

And

for my $person (keys(%phone_numbers)) { #$person clearly tells the mea
+ning of the hash key
    $phone_numbers{$person}...
}
