Abstract
This proposal suggests to add symbols into Python.
Symbols are objects whose representation within the code is more
important than their actual value. Two symbols needs
Well, thank you all !
I still feel it could be good for Python to have some kind of symbols
built in, and I will try to expose that to the python-dev list, to see
their reaction.
But in the different solutions proposed, the one I prefer is probably
the definitions of contants in a class to group
When you need some symbols in your program, what do you use in Python ?
For example, an object get a state. This state is more readable if
expressed as a symbols, for example "opened", "closed", "error".
Typically, in C or C++, I would use an enum for that:
enum OBJECT_STATE
{
opened, closed, er

The problem I find with augmented assignment is it's too complex, it's
