Okay; I'll open an issue for deprecation in 3.2 and removal in 3.3.

Can this sneak in under the 'incorrect language semantics' exemption for PEP 3003 (the moratorium PEP)? If not, then deprecation presumably has to wait for 3.3. It seems that in spirit the moratorium applies more to language additions than to removals/limitations. The goal being that alternate implementation stop chasing a moving target in terms of features. So IMVHO it is fine for 3.2. Removing it certainly seems in keeping with the goal of making life easier for alternate implementations. (Out of curiosity, does anyone know what IronPython does here?)

Same as Jython and PyPy:

IronPython 2.6.1 (2.6.10920.0) on .NET 2.0.50727.4927 Type "help", "copyright", "credits" or "license" for more information.

dict(**{1: 'hi'}) Traceback (most recent call last): File "", line 1, in TypeError: expected string for dictionary argument got 1
