But that should be a choice, defined by the scripting for a particular =
flow, not in the core code. There aren=E2=80=99t just these two =
mechanisms, either. Allegro, for example, has a much more elaborate =
mechanism that keeps track of the symmetries within slots (which input =
to the NAND you use doesn=E2=80=99t matter), as well as the symmetries =
between slots (which slot your use doesn=E2=80=99t matter).
