For those of you not at the Language Summit at PyCON the day before yesterday, there was talk of identifying non-portable behaviour, such as relying on CPython's reference counting garbage collector to close files for you as soon as they become unreachable. And then warning about them.
We have a real live user who has a large code base that relies on the CPython behaviour that an object's __radd__ method will take precedence over a list's inplace add behaviour. The thread with the whole gory details begins here: http://codespeak.net/pipermail/pypy-dev/2011q1/006958.html My inclination is to declare code that relies on this as broken, rather than patch every wretched container type in PyPy. Can this become blessed as a 'you shouldn't have done this'?
