in reply to .. in reverse

I wonder about the comparative efficiency of @A[reverse3 .. 50] and reverse @A[3 .. 50]?

Well It's better than the Abottoire, but Yorkshire!

    Of course they aren't always interchangable.... One can be used as an lvalue the other can't. 
    #!/usr/bin/perl -wT
use strict;

my @a             = 'a'..'f';
@a[reverse 5..10] = 'A'..'F';  # can you rewrite this line?

print "@a\n";

__END__

a b c d e F E D C B A

      Yes! But It's not as pretty. 

      #!/usr/bin/perl -w
use strict;

my @a       = 'a'..'f';
#@a[reverse 5..10] = 'A'..'F';  # can you rewrite this line?
splice @a, 5, 10-5, reverse ('A'..'F');

print "@a\n";
__END__

      @a[5..10] = reverse 'A'..'F';

      Not that it really addresses the point...
