There is the solution suggested by Bob Showalter, clearing the values
manually. The ideal solution would be to use lexical variables that go out
of scope before it starts another iteration.
As a simple example, consider some code that iterates over a list of files,
opening each and processing each line of the file.
foreach my $file (@files) {
open(FILE, $file) || die("open \"$file\": $!");
my @counter;
while (<FILE>) {
# do something to fill @counter
}
close(FILE);
}
Because @counter is lexical to the foreach block it's cleared on each
iteration of the foreach.
