say
Like print, but automatically appends a newline after the output.
Behaves identically to print except that a newline character is
appended after all output (including any $\ record separator).
Requires use feature 'say' or use v5.10 or later in perl5.
Internally delegates to pp_print, which detects OpCode::Say
and appends the newline to the correct filehandle.
Synopsis
say "hello world"; # prints "hello world\n"
say STDERR "debug info";
say $fh @data;
