INITIALPATH:7:22: error:
• Ambiguous type variable ‘t0’ arising from a use of ‘pyfToString’
prevents the constraint ‘(PyFToString t0)’ from being solved.
Probable fix: use a type annotation to specify what ‘t0’ should be.
These potential instances exist:
instance [safe] PyFToString String -- Defined in ‘PyF.Class’
...plus two instances involving out-of-scope types
(use -fprint-potential-instances to see them all)
• In the second argument of ‘(.)’, namely ‘pyfToString’
In the expression: (PyF.Formatters.formatString (PyF.Internal.QQ.newPaddingKForString PyF.Internal.QQ.PaddingDefaultK)) Nothing . pyfToString
In the first argument of ‘putStrLn’, namely ‘(((PyF.Formatters.formatString (PyF.Internal.QQ.newPaddingKForString PyF.Internal.QQ.PaddingDefaultK)) Nothing . pyfToString) (truncate number))’
