Certainly 3.x, but not 2.7. Why not 2.7? It is a perfectly-backward-compatible change: no currenly-working code could possibly break if cmath's restriction was relaxed. It's a new feature. That is an assertion; I can dqually assert that the current over-strict typechecking is a bug, because it doesn't conform to the semandics of 'complesnew'.

Maybe, but an assertion made by the 2.7 release manager tends to be the stronger one :)
