What I'm saying is that valuetype inheritance doesn't make any sense at all.
Doing so goes against the CLR type system and is doomed to fail.

Encoding a OO type hierarchy using valuetypes is plain wrong.

Let me restate that. It's not a bug in mono, the CLR is designed this way
and there is no compeling reason to implement such broken behavior.
