Every time you redefine it, it is redefined. And depending on
implementation the variable could be valid only inside of the loop. If not,
then it is what it is defined.
For idx as integer = 0 to things.max
Above idx is integer.
For idx = 0 to others.max
Above idx is either undeclared or integer, depending on implementation.
For each idx as float in floatarray
Above idx is float.
