Well, solveset_real assumes that you are working in a real system, that means both the equation and the solutions are in a real domain. So solveset_real expect users to input equations like `exp(I*x) = 0` and it should probably raise an error or maybe the doc string needs to be updated. As you have figured out for yourself if someone wants to work in the complex domain they can always use solveset_complex.
