Okay.

print with zero arguments prints $_.

print with more than zero arguments prints its arguments.


You're trying to give print zero arguments, so it prints $_:

print () . "\n";
      ^^

And, at the same time, more than zero arguments, so it prints a newline:

print () . "\n";
         ^^^^^^


But, of course, you can't give print zero and more than zero arguments at
the same time.  If you want print to print anything other than just $_, you
have to give it the arguments you want it to print.

print "$_\n";
