the little known << >> operator.

As of Perl 5.22, that statement might be a little confusing; from the 5.22.0 perldelta:

New double-diamond operator

<<>> is like <> but uses three-argument open to open each file in @ARGV. This means that each element of @ARGV will be treated as an actual file name, and "|foo" won't be treated as a pipe open.

    The <<>> operator doesn't take arguments. It only makes sense for the magical processing of STDIN and @ARGV files, not for an explicitly given file handle.
