[issue17959] Alternate approach to aliasing for PEP 435

[Nick Coghlan]

Nick Coghlan added the comment:

That's a terrible way to express aliasing, because it's really unclear that "rectangle" is the canonical name.

By contrast:

  class Shape(Enum):
    rectangle = 2
    oblong = rectangle

leaves no doubt as to which is canonical and which is the alias. You never need to go beyond two assignments, as you can still use multiple target assignment for the aliases.
