So, given that a lot of times $UNIQUENAME is just the name of the port, and a lot of ports have hyphens in their names, how is this meant to be dealt with?

I take back part of that last bit.  I’ve found a couple cases ( and that use the ${UNIQUENAME:U:S,-,_,} construction to allow setting safe variables. doesn’t use the same construction when referencing ${$UNIQUENAME}_SET and ${$UNIQUENAME}_UNSET.

So, I’m still back at my earlier question… how is this meant to be dealt with?
