I would imagine Python's approach to introducing new language features had a lot to do with it. Having to go through the PEP system takes some time, and changes like these tend to be reserved for minor-version releases. All in all, I love the PEP system, it's such an open concept and I've been surprised by the amount of quality proposals that get implemented. Wish Go had something like it.
