I would think the fact that the '[decorators]' syntax can be implemented in
pure Python (no changes to the interpreter) for existing Python versions
would give more weight to it. That is, if someone wants to implement a
decorator that's forwards and backwards-compatible, that's possible with
the list syntax, but not the @ syntax.
