.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
It's possible to use a variable that's already been declared as the iterator
for a foreach loop, but this will localize the
variable to the loop and its value will be reverted after the loop is done.
Always declare the loop iterator in the lexical scope of the loop with \f(CW\*(C`my\*(C'\fR.
