What comes to mind at once is to allow a complex number to be constructed
in rectangular form and then matched in polar form, or vice versa.
At present, the rectangular form is privileged, and adding your own
view rules only makes the polar form privileged.  There is no way to
make them equals.

And now here I was, in a country where a right to say how the country should
be governed was restricted to six persons in each thousand of its population.
For the nine hundred and ninety-four to express dissatisfaction with the
regnant system and propose to change it, would have made the whole six
shudder as one man, it would have been so disloyal, so dishonorable, such
putrid black treason.  --Mark Twain's Connecticut Yankee
