An alternative to your &find_first_index that I prefer (for smaller lists) is 

    use List::Util 'first';

    sub find_first_index {
        my $target = shift;
        first { $_[$_] eq $target } 0 .. $#_;
    }

    # Simple enough to write inline:

    my $idx = first { $ary[$_] eq $target } 0 .. $#ary;

I don't know about any efficiency issues though.

Update: Fixed a off-by-one bug in the sub and added parenthesis.
