Hello all,
While attempting to make a wrapper for opening multiple types of
UTF-encoded files (more on that later, in a separate post, I guess), I
ran into some oddities with the `codecs` module, specifically to do
with `.register` ing `CodecInfo` objects. I'd like to report a bug or

I object: conceptually, the "slots" of a class are set in stone, but
the `__slots__` attribute of a class object is just an attribute, and
any iterable (as long as it yields valid identifier names) can be used

What happens if you work on the commandline (Terminal)?

Now, the first way that comes to my mind is simply overloading the class and

The other way is to create an object and set it more manually (obj.regexps =
