that is done intentionally, one reason I could think of is to
make the module be able handle more different types of printings using
smaller function names, 'xpretty' ('from sympy.printing.pretty import

But for this

But probably the solution is what is returned for the `solveset_complex`

solveset_complex(exp(I*y), y)

and it should probably raise an error or maybe the doc string needs to
