That's also a possible solution, and the one that I'd personally be happiest with. The main problem is that this has the potential to break code: lists containing both floats and Decimals are sortable in 2.6, but would no longer be sortable in 2.7. If such breakage is deemed acceptable then I'd happily backport the exception; I really don't have a good feeling for how much real-world code could break, if any. > Also supporting comparisons but not other mixed operations is going to > be confusing.

The current 2.x behaviour has provoked complaints from a number of different people in various different fora (I recently saw this come up on StackOverflow), and after initially being skeptical I'm now convinced that it would be a good idea to change it if at all possible.
