in thread grep instead of foreach?

That is a cool writeup.

I have never seen this before: 

my %sorted_index;
@sorted_index{@sorted_array} = 0..$#sorted_array;

Can you explain to me how it works? Is it in the documentation?

Re: Re: Re (tilly) 1: grep instead of foreach? - hash slices

    is using a hash-slice there. The idea is: to address more then one entry in the hash at once. a simple example: 
    my %languages;
$languages{'python'} = 'boring';
@languages{'perl', 'perl6'} 
   = ('cool', 'real soon now');
# this is short for
( $languages{'perl'} , $languages{'perl6'} )
    = ('cool', 'real soon now');
# or
$languages{'perl'}  = 'cool';
$languages{'perl6'} = 'real soon now';

    There are also array-slices.
