Include remarks from (or compare to) extensible-streaming

[schlichtanders]

From researching what has been implemented around freer-effects I stumbled upon
https://github.com/michaelt/extensible-streaming
mentionened here at reddit while discussing some benchmarks (there extensible-streaming was faster than freer).

A deeper look at the implementation of extensible-streaming, i.e.
https://github.com/michaelt/extensible-streaming/blob/master/Data/Functor/Effs.hs and https://github.com/michaelt/extensible-streaming/blob/master/Streaming/Extensible.hs (that is the whole implementation),
suggests that the author had a lot to say how to even "improve" or alter freer in a for him sensible manner.
The code is extremely simple and extremely well documented.

Further researches through the web however haven't revealed anything more on the relationship between extensible-streaming and extensible freer-effects. Especially no one from the freer side seem to have ever reacted on extensible-streaming (to the best of my knowledge).

Do you have some remarks / more details on this? Maybe extensible-streaming is the way to go?
