I still don't understand the deal with the grepping. Why not just use a hash? 

sub rebind_closure {
    my $sub = shift;

    # Let Perl do the odd-numbered hash error handling for you!
    my %replacement_pairs = @_;
   
    my @rules = keys %replacement_pairs;
    my @replacements = values %replacement_pairs;

    # ...
}
