On the other hand, block-scoped variables are implemented in:

- very long list of other languages...
How many of these languages don't require any sort of variable declaration for all but a tiny minority of variables?
The aim of the block scoping proposal is to make Python *not worse* than these other languages, instead of adding funny workarounds again.
One of the ways in which Python is *better* than these languages is in not requiring variables to be declared. Let's not make the proposed Python *worse* than the current version of Python, by making variable declarations common.
