Actually, most arguments for local are centered around managing by types
rather than types and elements.

I assume you mean named types since there are no such thing as global
types.

I would be interested in any research related to polymorphic treatment
of types other than Arofan's paper since my google can't seem to find
any.

Once again, just because a tool supports a feature, that is not a
justifiable reason for using the feature.  Else we will just use <any>
and allow customizers free reign.
