Shouldnt it read:

my @matches = grep { $names[$_] =~ /$pattern/ || 
   $desc[$_] =~/$pattern/ } 
    0 .. $#desc;

If not, why not?

    Recall that 0 .. $#array; gives you a list of all the values between 0 and the maximum index of @array, or, in other words, the list of the indexes of @array.

    That bit of code assumes (and I made this assumption explicit) that the members of @names map 1:1 onto members of @desc; and if that is true, then 

    0.. $#names

    and 
    0 .. $#desc

    [download]

    yield up the same list, so either is acceptable.

    HTH!
