It's a nice example why scoped variables would be in fact better,

loop is implemented.
Using only the variable local to the loop would cause a compiler error, while
using only the variable defined in the function body would not even cause a
warning but leed to unwanted results.
That does not need inlined variables.
The compiler already has a warning about uninitialized vars. If not
detected after a for loop, this should be improved (rather than adding
some other workaround).
And there is a command line switch to tread warnings as errors. So that
problem is perfectly solve-able.
