-------------------------+--------------------------------------------------
Reporter: heatsink | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler (Type checker)
Version: 6.8.2 | Severity: minor
Keywords: | Testcase:
Architecture: Unknown | Os: Unknown
-------------------------+--------------------------------------------------
In the following code, a function has been applied to zero arguments,
which the type checker suggests is too many.
{{{
Prelude> foldr (>>=) [] []
<interactive>:1:6:
Occurs check: cannot construct the infinite type: b = a -> b
Probable cause: `>>=' is applied to too many arguments
In the first argument of `foldr', namely `(>>=)'
In the expression: foldr (>>=) [] []
}}}
