tcfail080.hs:27:1: error:
• Could not deduce (Collection c0 a)
from the context: Collection c a
bound by the inferred type for ‘q’:
forall (c :: * -> *) a. Collection c a => a -> Bool
at tcfail080.hs:27:1-27
The type variable ‘c0’ is ambiguous
• In the ambiguity check for the inferred type for ‘q’
To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
When checking the inferred type
q :: forall (c :: * -> *) a. Collection c a => a -> Bool
