an erlang monad?

Just a thought about this.
It is important to be able to access the state even somewhere in-between the
sequence, and it should be easy to do so too.
The reasons are two:
* one may need this state later on (I almost never have more than 3 levels
where the intermediary state isn't needed)
* easily inserting (and removing) debugging traces is very useful for finding
out what went wrong.
