RecordDotSyntaxFail8.hs:37:3: error: [GHC-39999]
• 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.
Potentially matching instances:
instance Show Ordering -- Defined in ‘GHC.Show’
instance Show Bar -- Defined at RecordDotSyntaxFail8.hs:22:41
...plus 29 others
...plus 12 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 $ ....baz.quux
In the expression:
do let a = ...
print $ ....quux
