Cliff,
I like the idea of changing the name to avoid the
common name "state". But it would seem that although
we may use an enum_state with "case()", it will most likely
be used for "transition()"
So why not make the new transition() statement
behave differently for enum_state and enum_state_onehot?
That way, we're down to only one change... and it
won't be too weird since the transition statement is
also new to have one that automagically does the
verilog reverse-case style.
I would still love to see a solution to the asychronous
reset problem.
