use warnings;
use strict;

my @[EMAIL PROTECTED]
 = qw/one two three four/;

print "$_\n" for grep /three/, @[EMAIL PROTECTED]
 tmp]# !$
../test5.pl
three

this works well. However, that goes through entire array.. right?
So there is no true way to squeeze in the ' last ' .. ?

main reason is to see if it's doable(I like some of perl's idioms) and 
whether it is possible
The other reason is because I have a big array which I have to look in 
by 3 different steps
and I wanted to avoid 3 foreach loop in a row which key depends on 
preceding code and wanted to just go
---- simplied version----

my $something = $_ for @[EMAIL PROTECTED]
 last if "$_" eq q/three/;
my $something1 = $_ for @[EMAIL PROTECTED]
 last if "$_" eq q/$something/;
my $something2 = $_ for @[EMAIL PROTECTED]
 last if "$_" eq q/$something1/;

Anyway, I will try your code and re****t back.

thank you.
