Funny how I feel no compulsion to pluralize the array name when I actually use the word 'array' in it.
I never use the word 'array' in an array name. It's completely redundant. The same goes for hashes and scalars: I never have %function_hash or $username_scalar.
I do use 'array' and 'hash' to name references. If you read $array in my code, you can be sure it's a reference to an array. Some people use $arrayref or even $array_reference, but 'ref' is useless information, imho, because a scalar simply cannot be an array. (Okay, I'm ignoring overloading now)
