A TypeCollision is used when we have a collision between two types with the same name. Currently this is only possible w/ generic methods that should logically have arity as a portion of their name. For eg: System.EventHandler and System.EventHandler[T] System.Nullable and System.Nullable[T] System.IComparable and System.IComparable[T] The TypeCollision provides an indexer but also is a real type. When used as a real type it is the non-generic form of the type. The indexer allows the user to disambiguate between the generic and non-generic versions. Therefore users must always provide additional information to get the generic version.
