 ok.  the implications are, to be able to follow through on that: no
Stage may contain sync.  at all.  anything that is chained together
(in the intended single-cycle fashion) must be pure combinatorial.
there must not be, under any circumstances, the use sync in the data
path, data chaining, valid/ready or valid/ready chaining.

 that in turn implies that *absolutely none* of the current Control
classes may be utilised (bugs or no bugs).

is there a way round that?
