How to get a parameters name in the parameter?

How do I get the tx name in a parameter.

I want to put the same expression in a bunch of different parameters and get the correct expression name returned.

Something like me.par.name where me is the par instead of the operator so I could put it in the ty parameter and it would return ty, or tx if it were in the tx parameter.

In the 2017.30000 series of builds we’ve added me.curPar. So you can do me.curPar.name.

SWEET. THANKS. AWESOME.
