FlowT in 2.4 is a very ergonomic alternative compare to Variant on the Left of Either. I like it a lot. Just want to bring up an enhancement for discussion.
Since it has a MonadIO instance, should FlowT also provide MonadMask instance (and its superclass instances)?
Hi,

btw, I'm not proposing that FlowT needs all n^2 mtl instances because Variant on the Left of ExceptT already serves that purpose well enough for now.
Thanks! Feng
