Lists are the most basic containers in perl syntax but not a variable's data type.

A list is not necessarily a hash, you can have odd numbers and dupplicate keys or irregular "keys"

Keys would also be more vulnerable to syntax errors.

Many other languages don't even know how to handle lists.

But you're free to implement the workarounds I've shown you.
