in thread Confused about unary +

It's not only true for any build-in subroutine, it's true for any user defined subroutine as well. Why perldoc puts the remark at print, and why the warning only occurs at print and friends has been a mystery for me ever since I started programming Perl.

    Thanks. I suppose that my question can thus be summarised as:

    Who are print's friends?

[d/l]
      printf

      Note also: 

      $ perl -wle 'print("a")'
a
$ perl -wle 'print ("a")'
print (...) interpreted as function at -e line 1.
a
$ perl -wle 'print  ("a")'
a
$

      You only get the warning if there's exactly one space between printf? and the opening paren.
