Perl >= 5.20 has the safer <<>> operator,
It was actually added only in Perl 5.22. perl5220delta man page says: 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.
