NAME ==== Hash::Restricted - trait for restricting keys in hashes SYNOPSIS ======== use Hash::Restricted; my %h is restricted = a => 42, b => 666; %h<c> = 317; # dies my %h is restricted<a b>; %h<a> = 42; %h<b> = 666; %h<c> = 317; # dies DESCRIPTION =========== Hash::Restricted provides a `is restricted` trait on `Map`s and `Hash`es as an easy way to restrict which keys are going to be allowed in the `Map` / `Hash`. If you do not specify any keys with `is restricted`, it will limit to the keys that were specified when the `Map` / `Hash` was initialized. If you **do** specify keys, then those will be the keys that will be allowed.
