RecordDotSyntaxFail11.hs:8:3:
Ambiguous type variable ‘a0’ arising from a use of ‘print’
prevents the constraint ‘(Show a0)’ from being solved.
Probable fix: use a type annotation to specify what ‘a0’ should be.
These potential instances exist:
instance Show Ordering -- Defined in ‘GHC.Show’
instance Show a => Show (Maybe a) -- Defined in ‘GHC.Show’
instance Show Integer -- Defined in ‘GHC.Show’
...plus 23 others
...plus N instances involving out-of-scope types
(use -fprint-potential-instances to see them all)
In the first argument of ‘($)’, namely ‘print’
In a stmt of a 'do' block: print $ (foo.bar.baz) a
In the expression:
do let a = ...
print $ (foo.bar.baz) a
RecordDotSyntaxFail11.hs:8:11:
