# Why region_plot dont work with absolute value of complex numbers?

Im trying to plot something like

```
var('y')
region_plot([x*abs(x+y*I)-cos(y) <= 5, y^2+e^x<=3],(x,-5,5), (y,-5,5),incol='lightblue',bordercol='blue')
```

but I get an errorType because the imaginary unit. I dont know how to fix it, any help would be appreciated.
