This would have the unfortunate side effect of only allowing changes to 
Python that allowed users to do things which are currently impossible.

Since Python is Turing-complete, this would effectively inhibit all 
further changes to the language.

Would you, say, remove "for" loops because they could be written as 
"while" loops. Don't forget the word "obvious" that appears in that 
catchphrase ...
