(Feature Request) - Convert to polar (phasor) notation in CAS

You have expressions that contain complex parts, but those can be in very varying forms and varieties. Whereas in home and numeric parts, the two values are intrinsically linked as a single object. That object has a flag that means "display in rectangular" or "display in polar". Hence nothing changes and it just toggles the bit on that individual object.

Bernard the CAS author could possibly extend the polar_coordinates/rectangular_coordinates to also work with vectors of vectors (there is no MATRIX object in CAS actually either, which is another major difference), but that will depend on him desiring to do so.

It will not be able to use the same display routines and keep the pairs together because that type of object just does not exist in CAS land...

That is pretty interesting, kind of bad news...

I really wished CAS handled phasor notation better since it is so relevant in many electrical engineering applications.

Meanwhile, I just found a possible bug. In CAS, I can write 1∠45 and execute. The calculator will change the notation to ∠(1,45). But if you try yourself to use this notation, it gives you an error. See below. Might worth taking a look?
