{
my @keys = qw/q w e r t y u i o p/;
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";
}
This produces the output
First is q ..
In the middle: w
In the middle: e
In the middle: r
In the middle: t
In the middle: y
In the middle: u
In the middle: i
In the middle: o
Finally, we have p.
But I like your solution of using an Iterator -- then it has the job of handling the 'first' and 'last' issues.
