I have a different view on the issue, but I don't want debate that here.
If you're interest, its at.

Yet another reason I can't wait for Michael's book to get done.

I suspected that. But do you think there is any chance we can get the
committee to reconsider? We do have new data: that many of the beginner
questions we get on this list are the result of confusing declarations
with assignments. This is a problem.
Prohibiting redeclarations isn't a full solution, but at least it
enables the compiler to reject many of these erroneous programs.
