Yeah, this thread is mostly a mess (what would nonlocals() return anyway?), but there is one serious suggestion in there. Maybe dir() should return a set.
Points in its favor:
- The results of dir() are non-repeating
- The order of items returned by dir() is not especially important
- It would make "method" in dir(obj) marginally faster
Points against:
- It would break code that tried dir(obj)[0] (but why would anyone do that?)
- Even though the order isn’t important for code, it’s convenient at the interactive prompt to see the methods of an item in alphabetical order for quick scanning.
Overall:
-0
My two bits.
