T8566.hs:32:9:
Could not deduce (C ('AA (t (I a ps)) as) ps fs0)
arising from a use of ‘c’
from the context: C ('AA (t (I a ps)) as) ps fs
bound by the instance declaration at T8566.hs:30:10-67
or from: 'AA t (a : as) ~ 'AA t1 as1
bound by a pattern with constructor:
A :: forall (r :: [*]) (k :: BOX) (t :: k) (as :: [U *]).
I ('AA t as) r,
in an equation for ‘c’
at T8566.hs:32:5
The type variable ‘fs0’ is ambiguous
Relevant bindings include
c :: I ('AA t (a : as)) ps -> I ('AA t (a : as)) ps
(bound at T8566.hs:32:3)
In the expression: c undefined
In an equation for ‘c’: c A = c undefined
In the instance declaration for ‘C ('AA t (a : as)) ps fs’
