@Gaussler I'm trying to get the same thing working with NewDocumentCommand, but it's not working so far \NewDocumentCommand{\inv}{s 0{#1}}{\IfValueTF{#1}{^{\prime-#2}}{^{-#2}}}.

See also difference between \prime and ' in math mode

In fact, a' is equivalent to a^{\prime}. Knuth made it this way precisely so that you can type a^{\prime 2} to get a'². You should never write a\prime, however, as this will put a giant prime to the right of your a.

Incidentally, is there a difference between a' and a\prime? I've been using the former this whole time, but I'm noticing people using the latter in this thread.

@V.Ch. You have a valid point. My keyval-based approach makes the most sense when writing papers with complicated constructions like \mathcal{C}_{/X}^{\mathrm{op}} or \mathcal{D}^{b,\ge0}(X). Then I find it blessing to be able to instead write something like \catC[over=\vX,op] and \der[bounded,positive degree]{\vX}. But that is entirely a matter of taste, of course. ;-)
