I'm using Perl version 5.12, and I get this error. My version of keys shows: 
       keys HASH
       keys ARRAY

The latest docs also support keys EXPR:

Starting with Perl 5.14, keys can take a scalar EXPR, which must contain a reference to an unblessed hash or array.
This test is not portable across all versions run by CPANTesters.
