Indeed, I tend to think that reg-names is a bad idea.

IIRC, the rule for "reg" is that entries must always have a defined
order, so that it can always be accessed by integer index. And given
that's true, allowing for reg-names just creates confusion since it
implies you can look up the index in reg-names and then read reg at that
index.

Now the same isn't true for clocks/clock-names for example, where it's
defined that there is no order, so you must search clock-names first.

Inconsistency in rules, uggh.
