[Haskell-beginners] using parametrized monads and Prelude.>>

Hello,
I would like to create few functions which use parametrized monads
(defined as in http://computationalthoughts.blogspot.com/2009/02/comment-on-parameterized-monads.html
) and export their functionality outside a module and use them in a do
statement.
For example three exported funtions :
func1 num = do
x <- get
put (show (x + num))
func2 num = do
x <- get
put (((read x)::Int) + num)
execWith0 actions = runState actions 0
And in an another module, which has Prelude imported :
k = execWith0 ( do
func1 10
func2 5)
Unfortunately this doesn't compile as in the second module >> is
different than in PMonad. Is there any way which I could make it work?
