[code for a classproperty]
Nice, if it is that simple.
Is there a reason why this is not in the standard library?
I haven't had a chance to test Peter's classproperty code yet, but I
don't expect it to be that simple. People have asked for it before, and
even Guido himself (the inventor of Python) has agreed that if it
existed he'd use it, but the proposals have (so far) always stumbled on
two factors:
- there are not a lot of uses for classproperty that ordinary property
isn't "good enough" for;
- its hard to get classproperty to work right.
What is "righ"?
In my case a read-only classproperty is enough. Inheritance should be supported.
I don't have a usecase for a setter.
