Dear Monks,

once in a while I try map and grep, but normally I avoid them becaus they are so complex.
Anyway, this time I tried todo the following with grep:
#! /usr/bin/perl 

use strict ;
use warnings ;

my @inp = ("abc_A_bla", "abc_B_bla", "abc_C_bla") ;

my %inp ;

$inp{$_} = 1 grep ( /\w{3}_(\w)/, @inp ) ;

foreach ( keys %inp ) {
    print "Found $_\n" ;
}

So, I would like to create a hash with the keys A, B and C. Running this gives an error near grep.
Can someone tell me what I do wrong here with grep?

Thanks
Luca
