OK.

OK i fully understand that.

pvesh does have a reverse map i would implement copy also as POST - then 
the reverse map gets broken.

sub reverse_map_cmd {
     my $method = shift;

     my $mmap = {
         GET => 'get',
         PUT => 'set',
         POST => 'create',
         POST => 'copy',
         DELETE => 'delete',
     };
