That is actually fairly common notation in fractional calculus, where we in fact can work with (d/dx)^alpha where alpha can be many things that aren't necessarily integer. 
Everyone agrees that Leibniz' derivative notation is superior, but what about for antiderivatives?pic.twitter.com/I9ZSGKLMqN

Do you recommend any textbooks on fractional calculus?

If you write dx/d instead of (d/dx)^-1 it works out perfectly lol

hahaha I was thinking of that same thing! but I decided against it, because it's not conventional.. but I agree it seems the most symbolically intuitive

Fractional derivatives seem easier to write in the notation on the right. Though D^{\alpha} (multi-index) notation is quite nice
