* patch by Aleksa Todorovic which adds the ability to reference current generic class. Each reference to current generic class is "translated" to appropriate specialization of that generic class. There are two tests as part of the patch to test that it works. The patch, also, rejects declaring generic inside another generic. 0010479 is easy to implement with this patch applied, resolves #11777
