in thread Perl's feature to determine, in current point of loop, that this is the last one?

Edge case behaviour might need some changes:

#!/usr/bin/perl use strict; use warnings; # 2022-0125: Handle First and List iems differently that everything # in between .. { # my @keys = qw/q w e r t y u i o p/; my @keys = qw/q/; print "First is $keys[0] ..\n"; foreach my $k ( @keys[1..(scalar @keys -2)] ) { print "In the middle: $k\n"; } print "Finally, we have $keys[-1].\n"; }
B:\>perl 11140865-single.pl First is q .. Finally, we have q. B:\>
