Builds upon the Parrot HLL identifiers. This mechanism will be used to fix various Rakudo issues when NQP-defiend objects are encountered. It will also replace the special-case perl6ize_type with a more general and more portable mechanism, that can work in an environment where all objects are 6model objects.
