[issue43908] array.array should remain immutable

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

Adding an extra flag seems like the sensible thing to do for 3.10

Longer term, we should decouple immutability from whether something is a heap type.
I don't know why we would care that it is a heap type at all. Which bit of memory it happens to sit in seems irrelevant to anything but the GC.

Erland, could you turn your patch into PR?
