Just so that I am not accused of being disingenuous.  That subject of
primitive type was raised early in the discussion, but only intended in the
context of the fact that Numeric arrays were prepared to except the
immutable built-ins as complex numbers and unprepared to accept the custom
class that was the same but mutable, as such.  It presented a practical
problem to me, and I was looking for practical solutions to it beyond the
one had I been working with but found not fully satisfactory.

But to repeat -

The course of these discussions had some real practical value to me, having
helped me come upon an idea for the implementation of the objects of the
complex plane geometric objects that I think better reflects the ground of
the mathematical ideas being explored, and with less of a performance
trade-off.  I could not want more, and I just hope I am not missing anything
important by being excited about getting to the implementation.

The small problem at the moment being the laptop on which I have my latest
working version ain't taking well to getting powered up.
