Yes.

I know, that this is recommended.  But maybe there is some kind of
"magic" which supports stdin?  If --filter is used, $InputFilename is
set to "-", maybe 
 open(IN, '<-')
works while
 open(IN, '<', '-')
is not supported?

At least "perldoc -f open" mentions only the first one:

               In the 2-arguments (and 1-argument) form opening '-' opens
               STDIN and opening '>-' opens STDOUT.

while there is no word about a similar mechanism with the 3-arguments
call of open().

Tschoeeee
