What way ? The foo=decorator(foo) workaround after the function's body
? That's hardly acceptable for common decorators such as staticmethod,
classmethod and other suggested ones (synchronized, cached, traced,
etc.). I don't mind the @ so much - I don't like it particularly either
- and I don't compare it to the alternative rejected decorator syntax
forms, but it's certainly an improvement over the pre-2.4 explicit
assignment *after* the function.
Properties are in the same boat with decorators. Although they are
great semantically, the current syntax is less than optimal.
Interestingly, Pyrex does much better in the readability department
The Property decorator recipe
pretty close to it, but I wouldn't mind a small addition to the
language syntax for something so useful as properties.
Keeping the language small is a worthwhile goal, but it should be
traded off with conciseness and readability; otherwise we could well be
content with s-expressions.
Just my $0.02,
