--- Comment #5 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
to make sure this thought is written down: i realised a few days ago,
some of the Case/Switch submodules for PartitionedSignal, particularly
Cat, Part and Assign, are approaching the gate density of full crossbars.
that isn't going to fly.

a way to reduce the number of required entries is needed: the option
to specify what combinations of mask are supported.
