#3973: Derive Typeable and Eq instances for TMVar, TChan (and TArray)
---------------------------------+------------------------------------------
Reporter: basvandijk | Owner:
Type: proposal | Status: new
Priority: normal | Component: libraries (other)
Version: 6.12.1 | Keywords:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
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.
