Scalaz StateT, no access to get / modifiy / put ?
In scalaz, is there a way to get access to:
blah: StateT[Future, state, result] =
_ <- StateT.get[state]
_ ...
It seems that only get modify etc. are only defined for State not StateT. I can find references to them for StateT in the source code but I can't figure out a way to import them. If I switch to cats, I can get access to StateT.get, but I'm in a project using scalaz.
Thanks

IIRC the way to use these operations in Scalaz is to pull the instance of MonadState and call methods on it directly:
val S = MonadState[StateT[Future, State, ?], State]
val blah = for {
state <- S.get
...
