Class decorators in Python 2.5?

Question

Is there a way I can make class decorators work on Google App Engine, which is limited to Python 2.5?

Answer 1

Decorators are just syntactic sugar. Just change instances of decorator usage, that is,

@decorated
class Foo(object): pass

becomes

class Foo(object): pass
Foo = decorated(Foo)

You can't, realistically, change the parser.

Though, you could automate the above process using the ast module (in a new version of Python).
