Description
I would like to propose deriving Typeable and Eq instances for TMVar and TChan because their MVar counterparts have them also.
The included patch bundle adds them using the DeriveDataTypeable language extension.
There are two extra patches in the bundle that derive a Typeable instance for TArray and derive an Eq instance for TArray. These are separate patches because I'm not sure about the latter.
