Thanks for the links, especially for the pure Python implementation. That provides a good model for similar classes.
I am just wondering why your implementation of complex numbers does not have "assignment operators" such as "__iadd", etc. By the way, I suppose my original post (where I wrote, "I'd like to make my class behave like the "complex" class.") could be construed to mean that I was implementing my own version of the complex class. But I only meant that I want it to "behave" like the built-in complex class with regard to referencing and copying (as my code example showed). My apologies for any misunderstanding that occurred. -- http://mail.python.org/mailman/listinfo/python-list
