That's a very recent change to C/C++ (1999 apparently), 
you used to be able to do that. In fact I hadn't realised that 
you couldn't any more! It was only when I wrote a test 
program I discovered you were right...

Yes. Once you create a name within a scope it stays 
there and loops or code blocks are not a separate scope 
in Python
