why not extending the syntax for classes, too ?

I'm lukewarm on the whole idea, but I think I'd prefer "as" to "is" in
this context. "is" is a very important (and very specific) operator in
Python, and it's being used as an auxiliar syntax hint in a context
totally different from that which the "is" operator actually takes.
The "as" keyword, on the other hand, already exists in this auxiliary
capacity for the "import X as Y" statement, making it a much better
choice as an auxiliar signal in a syntactic context than a keyword that
already means something very specific and wholly unrelated.
