Er wot?
If I run the following code in Python 3.4:
x:int = spam.method(?) - 1
how is the 3.4 interpreter supposed to know when the x:int and the (?)
syntax were introduced? I can tell you when x:int is introduced (Python
3.6) but I have no idea when (?) will be introduced, or what it will mean.

Suppose that version 4.5 introduces |: syntax and version 4.8 removes it
again because it was a terrible idea. And 4.9 introduces unless
expressions. I write this:
x = spam |: eggs unless ValueError then cheese
What syntax error should Python 4.0 give?
