Dear Monks,

In the following example I try to count the number of bs. And I tried to do all this on one line:
#! /usr/bin/perl 

use strict ;
use warnings ;

my @a ;

$a[0] = "a" ;
$a[1] = "a" ;
$a[2] = "b" ;
$a[3] = "a" ;

my $b = 0 ;

$b ++ if ( $_ eq "b" ) foreach @a ;


print "$b\n" ;

Can someone explain to me why this is just wrong and if it is not too much to ask, what is the solution ?

Thanks
Luca
