In scripts it breaks POSIX, conflicts with the coproc operator in kshes, and 
applies the redirections in an unintuitive order since the same operator 
redirects stdout first, then applies the stderr redirect after other 
redirections. It isn't very common to dump multiple streams into one pipe. I 
suggest avoiding |&.
