ISTM, the whole reason people are asking for a String ABC is so you can write isinstance(obj, String) and allow registered
string-like objects to be accepted.
The downside is that everytime you want this for a concrete class or type, it is necessary to write a whole new ABC listing all of

I'm willing to meet you halfway. I really don't want isinstance(x,
str) to return True for something that doesn't inherit from the
concrete str type; this is bound to lead to too much confusion and
breakage. But I'm fine with a String ABC (or any other ABC, e.g.
Atomic?) that doesn't define any me

Probably true. It was an attractive id

I propose the following empty abstract classes: String, Datetime, Deque,
and Socket.

Sounds like a mini-PEP is in place. It should focus on the code to
actually define these and the intended ways to use them.
Okay, will run a Google code search to see if real code exists

Would anyone mind if I did add a public C API for gc.disable() and
gc.enable()? I would like to use it as an optimization for the pickle

GC while loading large pickles). Of course, I could simply import the

The principal purpose of an abstract base class is to support multiple
