Disable messages with GHC API

In Intero, after loading modules, for each one I run the following function: https://github.com/commercialhaskell/intero/blob/300ac5a/src/GhciInfo.hs#L75... If there are warnings or any output, they get outputted. As they are already outputted by regular :load, I don’t need the same output twice. How do I disable non-severe output for any GhcMonad m => m a? I’m using GHC 8.0.1 presently. I tried the following before calling getModInfo, expecting there to be no output anymore: + GHC.setSessionDynFlags + df {log_action = \ref dflags severity srcSpan style msg -> return ()} And this had no effect. I tried some other things but ran out of patience to keep a record of them all. Ciao!
