[hibernate-dev] UserCollectionType mapping for Ceylon

[Gavin King]

Ah, OK, thanks for the link, Vlad, now I think I sorta maybe see why.
With XML-based mappings, the semantic "kind" of collection is explicit
(<list/> or <set/> or whatever) whereas with annotations that is
determined by looking at the property type. The UserCollectionType
doesn't actually have this information.

So then I guess I'm going to need a bit of a deeper hack to make this work.
