True in general, but....

- in general, a declaration such as

     int x;

doesn't look like an assignment statement

- the idea of the same variable being declared multiple times in the 
same instance of being in the same scope is alien to many

- there are also static local variables, which aren't reset each time


Moreover, your claim that the _body_ of a for loop doesn't create a 
scope would also mean that ScopeGuardStatements and scope (fka auto) 
object references within the body are not processed at the end of each 
iteration, but saved until the end of the whole for loop.  Absolutely 
not the behaviour I'm experiencing.
