Yes, I realize this discussion is quite theoretical in nature. Some of
the more 'emotionally engaged' participants might do well to keep that
in mind as well.

Of course if a conversion tool falters on even a single construct,
automated conversion is not going to be reliable, and thats going to
be a pain. But whatever python 4 will be like, its not going to be
backwards compatible by definition; and at least I dont think this
proposed change will contribute to the trouble of conversion between
the two. It is really quite a superficial syntax tweak.
