I would expand your definition of monadic to:

operation can be altered by the results of the operations preceeding it.
IMO your definition matches more applicative.

instance (BinaryDefer a, BinaryDefer b) = BinaryDefer (a,b) where
put (a,b) = put2 a b
get = get2 (,)
size x = let ~(a,b) = x in size a + size b
putFixed (a,b) = putFixed2 a b
getFixed = getFixed2 (,)
in `size` function, what does the `~` mean ?

return value?
