[Python-3000] ordered dict for p3k collections? (original) (raw)

I hope that Python gets a sorteddict and a sortedset.

It doesn't make sense for Python to have sorteddict or sortedset. You see, dict can have keys which cannot be ordered (keys can be heterogeneous, in which case Py3K may raise TypeError; ordering doesn't make sense for the objects used as keys) and same goes for set elements.

Sorting makes sense only as a run-time operation, in which case, the programmer should be prepared to handle appropriate exceptions.

Btw, would you like a dict or set for which you have to handle exceptions at every insertion?
