#45707 — Case insensitive dict

I was doing some work with the ldap module and required a ci dict that was case
insensitive but case preserving. It turned out the cidict class they implemented was
broken with respect to pop, it is inherited and not re implemented to work. Before
I set about re-inventing the wheel, anyone know of a working implementation?

I noticed twisted has one but it seems to omit pop.

Thanks!

class my_cidict(ldap.cidict):
    """Fix problems with pop."""
    def pop(self):
        # insert code here


You don't have to re-invent the entire wheel just to fix one broken 
spoke :-)

Other than that, no, I don't know of any case-insensitive but preserving 
dicts. If you do decide to write one from scratch, please consider 
releasing it as Open Source (I recommend GPL or MIT licences), either as 
a module on PyPI or as a recipe on ActiveState.

Thank you.
