tcfail125.hs:1:14: Warning:
-XDatatypeContexts is deprecated: It was widely considered a misfeature, and has been removed from the Haskell language.
tcfail125.hs:11:4:
No instance for (Show a) arising from a use of ‛LiftObs’
Possible fix:
add (Show a) to the context of
the type signature for f :: Obs a -> String
In the pattern: LiftObs _ _
In an equation for ‛f’: f (LiftObs _ _) = "yes"
