#2261: Foreign.C.Error.Errno should be an instance of (Eq,Ord, Show... others?)
-------------------------------+--------------------------------------------
Reporter: TomMD | Owner:
Type: proposal | Status: new
Priority: normal | Component: libraries/base
Version: 6.8.2 | Severity: trivial
Keywords: Foreign, Errno | Testcase:
Architecture: Multiple | Os: Multiple
-------------------------------+--------------------------------------------
Errno, the Haskell encapsulation of the CInt 'errno' value, should be an
instance of the commonly used type classes so higher level data structures
that include it aren't bothered.
This change will break code that has custom instances for Errno, but this
should be little, if any, code.
