In practice, GNAT will almost always give a warning in this
case. If the outer variable is not referenced at all, then
that will certainly generate a warning. If the outer variable
is referenced after the loop, then a warning will be generated
about reference to an uninitialized variable.

This will not catch 100% of cases, but it's very close
