parameterized Helper traits

[Brian ROONEY]

Hi,

How does one get the helper traits for a parameterized type?  Here I am using 
the helper:
Moose::Meta::Attribute::Native::Trait::Hash
For HashRef

The hash actually contains parameterized CodeRefs so I would like to use: 
Moose::Meta::Attribute::Native::Trait::Code
For CodeRef

Is this possible?
Thanks

        traits                  => ['Hash'],

        isa                     => 'HashRef[CodeRef]',  
        required                => 0,
