I use the State monad in a lot of places, but when I use it with the lens library, I find myself writing code like:

myFunc :: StateT MyState ([ResultType])

myFunc = do

   st <- get

   case st ^. some_property of

      True -> do

            my_value .= "Hello"

      True -> do

            my_value .= "Goodbye"

         

I want to do something based on a 'state-variable', but I have to write 'get' -- is there a pattern that allows me to avoid the intermediate 'st' variable? 

I want to write something like:

but that won't compile.

Best wishes,

Mike
