No, just the obscurity of these methods: the full Python __add__/__radd__ semantics are more than a little tricky. They are impossible to implement statically, because in order to know which one to call first you need to know the two exact subclasses of the arguments, which you only know at run-time. The RPython approach so far has at least a clear message: no special methods, apart from __init__() and __del__(). I'm not against adding a few of them, to be honest; e.g. __getitem__() would be my favorite. But then they should be fully implemented. For example, I just realized that without the full rtyper solution, your patch can work for str(x) but not for '%s' % (x,), which looks rather inconsistent.
