in thread **HomeWork** Printing the found input from an array

# works as expected!

Which depends on you expectations:

my @myCities = (1 .. 2);
my $city = "before";  # now is scoped to the whole package!
foreach $city ( @myCities ) {
   # do your stuff
   $city = "after";
}

print "$city"; # works as expected!

# ... unless you expected it to print "after"
# ... actually it prints "before"

This is a Perl peculiarity I was once also bitten by.

Actually Perl will localize the $city for the scope of the for-loop. See perldoc perlsyn.
