Hi Alejandro,
That instance (and others) should be in HEAD [1] and will be included in
the next release.
As for considering Free at “the bottom of the stack”, I’m not sure I
understand what you mean. Nonetheless, I think FreeT f m a can be
considered as m actions *delimited* by f actions. Thus Free f a being
simply FreeT f Identity a is just a “sequence” of f actions to be
interpreted.

Dear Café, I'm continuing my travel through operational and free, and was wondering: which is the reason why there's no instance such as
(Functor f, MonadReader e m) => MonadReader e (FreeT f m)
included in the 'free' package? It seems reasonable to me to have those instances. At least, there's the corresponding one for MonadIO.
Should Free be considered as some monad to have 'at the bottom of the stack' as IO is?
Thanks in advance.
