`Either` complex logging.

[bandophahita]

Consider a series of actions passed into Either which ALSO contain Either

Either(act1, Either(act5, act6).or_(act7, act8), act2).or_(act3, act4)

The describe() of the above would read as follows:

Either doAct1, either doAct5, doAct6 or doAct7, doAct8, doAct2 or doAct3, doAct4

It would be really nice to make that a bit more readable as to which parts are grouped up:

Either (doAct1, either (doAct5, doAct6) or (doAct7, doAct8), doAct2) or (doAct3, doAct4)

or perhaps

Either (doAct1, either (doAct5, doAct6 or doAct7, doAct8), doAct2 or doAct3, doAct4)
