I wonder how many reasonable real-life scenarios actually exist for this
feature?
My personal use would be for COM, to implement case-insensitive namespaces.
In some cases, case-insensitivity is actually part of the implementation
specification, and I can imagine other scenarios where case insensitive
namespaces are "reasonable" even in the face of Python's excellent decision
not to go this route.
I wonder is this is actually the root of many requests to see this feature
implemented? If not, it would be interesting to see what the competing
desires really are.
Mark.
