[Ironruby-core] getting the runtime type

Is the current best practice for this to create a custom class for any Ruby
types that need CLR integration, or should we use
IronRubyInline<http://github.com/rvernagus/IronRubyInline>?
I suppose it depends on your use case, but I would think the latter is
probably the best option. Thoughts?
