I've got two questions about the Perl open function:
1) I seem to remember from Perl Best Practices that the 3-argument version of open is better than the two argument version, e.g.
open(OUT, '>>', $file);
vs.
open(OUT, ">>$file");
Why is that? I was trying to tell somebody to use the 3-argument version the other day but couldn't seem to back it up with anything.
2) I also seem to remember autovivified filehandles being favored over bareword filehandles (they called something different)? And also couldn't remember why, e.g.
open(my $out, '>>', $file);
vs.
open(OUT, '>>', $file);
Is it a strict thing? I seem to remember being able to use OUT with strict but I can't remember.
