T5300.hs:11:7:
Could not deduce (C1 a b c0)
arising from the ambiguity check for ‛f1’
from the context (Monad m, C1 a b c)
bound by the type signature for
f1 :: (Monad m, C1 a b c) => a -> StateT (T b) m a
at T5300.hs:11:7-50
The type variable ‛c0’ is ambiguous
In the ambiguity check for:
forall a b (m :: * -> *) c.
