Comment:
This was fixed in #13902. The error message now reads:
{{{
Bug.hs:5:9: error:
• Couldn't match expected type ‘Bool -> t’ with actual type ‘Bool’
• The expression ‘id @Bool’ is applied to two arguments,
but its type ‘Bool -> Bool’ has only one
In the expression: id @Bool True False
In an equation for ‘wrong’: wrong = id @Bool True False
• Relevant bindings include wrong :: t (bound at Bug.hs:5:1)
|
5 | wrong = id @Bool True False
| ^^^^^^^^^^^^^^^^^^^
}}}
