I like this list a lot. I also find myself raging at awful lambda and the lack of switch. No, it wouldn't make the language any less "pythonic" to make them useful.
It also seems un-Pythonic to have to implement something in a less-obvious way. Choosing an action based on a one item from a set of possible inputs means either a dict that maps to lambdas or function variables or a big chain of if-else. Neither of those options are optimal.
