On the latest Haskell interlude podcast, the guest was talking about how using the ReaderT monad specifically introduces safety issues. My ears perked up because I’m right in the middle of leaning on it heavily in one of my Haskell projects.

@demesisx @lysdexic No safety issues mentioned around ReaderT. The speaker was talking about how stacking monad transformers mtl-style can generate unnecessary closures that GHC can't optimise away.
