Couldn't match expected type `Int' with actual type `Char'
In the expression: 'p'
In an equation for `a': a = 'p'
../../typecheck/should_run/Defer01.hs:18:9: Warning:
No instance for (Eq B) arising from a use of `=='
Possible fix: add an instance declaration for (Eq B)
In the expression: x == x
In an equation for `b': b x = x == x
../../typecheck/should_run/Defer01.hs:28:5: Warning:
No instance for (Num (a -> a)) arising from the literal `1'
Possible fix: add an instance declaration for (Num (a -> a))
In the expression: 1

No instance for (Num a1) arising from the literal `23'
The type variable `a1' is ambiguous
Possible fix: add a type signature that fixes these type variable(s)
Note: there are several potential instances:
