Oleg, in `Freer Monads, More Extensible Effects`, describes the implementation of Fluet and Morrisett’s “monadic regions”, which are like a nested `ST` monad.

I didnt find this function in https://hackage.haskell.org/package/freer
but it was in a paper "Freer Monads, More Extensible Effects" http://okmij.org/ftp/Haskell/extensible/more.pdf

We’d like to be able to aggressively optimize languages by applying certain equalities to reduce the term tree. However, you can’t in general do optimizations (or more broadly, analyses) of languages …

We need more quantity. As a first step, we can collate benchmarks from papers.

As I understand point of Free monad is to not write monad instance for our data structures, so why do we have chain defined on `State`?

Hi, thanks for this interesting library.
Currently, we can only handle effects purely since we can't use IO inside hander.
Can we have `IO`-like effect at the bottom of effect stack, and a runner…

I find myself wanting to have values with a very specific list of effects, to constrain what my users can do, e.g. `Eff '[E1, E2] a`.
However, I then have issues *interpreting* those: if `E1` can …

I really want to like `freer-simple`, but I can't until it infers at least as well as idiomatic mtl usage. The big problem at the moment is `Member`:
```haskell

We measure as slower than `mtl`—apparently on average?—and I want to know where and why that happens. Can we chip away at that? Can we fix it entirely?
It's not likely to matter a ton for consumers…
