I intended to send this to the list, rather than just to John. -- vincent

rectangular and polar complex numbers.

I've never seen a Scheme system that did distinguish between these two representations, but I'm grateful for the comprehensive list. Since these are representational issues, there should be no such distinction internally; it should be the job of NUMBER->STRING and STRING->NUMBER to handle them.

I have an upcoming proposal about NUMBER->STRING that will, I think, address this issue.
