| Subject: | Delegating 'accessor' method of native Hash rejects values as invalid keys |
The native Hash trait's method 'accessor' rejects its $value argument as
being an invalid key with the message "The key passed to accessor must be
a defined value".
That is, $obj->delegated_accessor(foo => undef); will fail despite the
definedness of 'foo'.
Attached is a simple test case; note that the bug exists in both forms of
delegation.
