I believe that << print {$fd} @list; >> does not concatenate all the arguments
into one big string and then prints it (similar to << print {$fd} join("",
@list); >>) but rather prints them one after the other (and even with printing
strings, there may also be buffering issues and other stuff like that - look
at http://perldoc.perl.org/functions/syswrite.html if you want to avoid that).
If you're still unsure, use Benchmark.pm to see which one is faster. But
remember that it's not a good idea to optimise your program prematurely. Did
you run into a specific problem with using << print {$fd} @list; >>?
