Classes
Interface of monads that support explicit sharing.
Interface to transform nested monadic data types. The provided
function trans
is supposed to map the given function on every
monadic argument. The result of trans
may be of the same type as
the argument but can also be of a different type, e.g. to convert a
value with nested monadic arguments to a corresponding value
without.
We provide instances of the Trans
class for some predefined
Haskell types. For flat types the function trans
just returns its
argument which has no arguments to which the given function could
be applied.

eval :: (Monad m, Trans m a b) => a -> m bSource
Lifts all monadic effects in nested monadic values to the top
level. If m
is a monad for non-determinism and the argument a
data structure with nested non-determinism then the result
corresponds to the normal form of the argument.
Monad transformer
Continuation-based, store-passing implementation of explicit
sharing. It is an inlined version of ContT (ReaderT Store m)
where the result type of continuations is polymorphic.
