How can I add extended operators(below). Generally speaking how can I implement such an operator (for example only one).
X+=Y
X-=Y
X*=Y
X\=Y
X%=Y
X&=Y
X**=Y
X=Y
X—=Y
X//=Y
X<<=Y
X<<=Y
By implementing, for example, __iadd__. See "Emulating numeric types" in the language reference.

The passstatement is usually a placeholder for future code and is used as a null operation.
But why it's not defined a type in Python. Should't it belong to None type?
Objects have types. Statements do not. pass is a statement, and does not have a type. (Also, None is not a type.)

As one may read in the Python Docs - __all__ variable is described as a list. Is there a reason (or does it even matter) for choosing this type over tuple? Both options work but tuple seems to be more valid as immutable type.

I was wondering today why some of the more useful decorators in the Python Decorator Library like #memoized haven't been added to the standard python library.
Is there a set of standards under which a module/function/decorator is evaluated in order to become a member of the standard library, or is it the informal decision of some group?
