Post subject:  redefine and kill in for loops

Consider a list l of rings or other objects.

def S;
int pos;
for (pos=1; pos<=size(l); pos++)

Is it necessary to kill and redefine S in each loop step?

If you want to assign l[pos] to s then the types must allow this.
For example, if s is of type int and l[pos] is of type string,
the assignment is not possible.
But if s will destroyed first and redefined as of type def
the assignment works and the type of s (which started as type def)
changes to string.
