Give a meaning to '&' in n-arg open case:
open($fh,"<&",$scalar);
$scalar can be:
- an integer which does "fdopen"
open($fh,"<&",2); # like open($fh,"<&2")
- something that will yield a file handle via sv_2io()
useful for dup'ing anonymous handles.
e.g.:
open(my $fh,"<&",\*STDIN);
open(my $dup,"<&",$fh);
