I think there is a way, but I’m not sure it’s really feasible.

One example of what you describe is the `adjoint` function and the `'` postfix operator  
[https://docs.julialang.org/en/v1/stdlib/LinearAlgebra/#Base.adjoint](https://docs.julialang.org/en/v1/stdlib/LinearAlgebra/#Base.adjoint)

Based on this [post](https://discourse.julialang.org/t/list-of-binary-infix-operators/32282/2), the infix/postfix/… operators are detected in the parser. Looks like `trans-op`/`ctrans-op` refers to the adjoint mentioned above.

So, in principle, one could add more individual rules to parse the code and recognize postfix operators, but since `x⁻¹` is otherwise just a normal variable name, I don’t think there is a way without hacking the parser…
