The name used as the assignment target in a for header…
““The name used as the assignment target in a for header line is usually a (possibly new) variable in the scope where the for statement is coded. There’s not much unique about this name; it can even be changed inside the loop’s body, but it will automatically be set to the next item in the sequence when control returns to the top of the loop again.””
