Python isn't less expressive for the most part except for lack of blocks(although can be emulated with decorators and def _), and ruby's strategic lack of parentheses and not being to add/change methods in c based classes. Python has just as much access to reflection, it has more powerful and arguably easier to shoot yourself in the foot inheritance (python has multiple inheritance while ruby only has mixins). Python also has method_missing in __getattr__. Arguably python tends to use these less often then ruby but I've definitely used both reflection and __getattr__. I've also once had to debug a really hairy multiple inheritance issue(in a test framework that used base classes to test different hardware features where you might want to have both you'd need to use multiple inheritance and then make sure they were initialized in the right order, multiple inheritance can get really annoying)
