I think this behaviour (modifying locals() at class scope) was actually
implicitly blessed in PEP 3115, even though that PEP doesn't explicitly
state locals() in a class body is required to grant access to the
namespace returned by __prepare__().
Perhaps the time is right for the locals() documentation to be more
explicit regarding when modifying its contents will affect the current
namespace?
- yes at module scope (effectively the same as globals())
- yes at class scope
- maybe (but typically not) at function scope
Cheers,
Nick.
