I am trying to avoid signals when I can. I use them in port maps, and

c or d. The solution I know for this requires an intermediate signal
for the actual selection. Is there another way?

multiple signals in an architecture is analogous to
multiple variables in a process
for the purposes of logic description.
for example, see:

Thanks for the example. It is a more elaborate template than the one I
was using.

So if it is analogous, and signals in an architecture don't solve the
problem of an additional delta delay, how can variables in a process
solve it instead?
