    If this warning sounded like: "print ([^)]*) interpreted as function" or "print (...) interpreted as function, where '...' is qr/[^)]*/" - it would be understandable. Because I don't know what do three points ('...') mean and am thinking that a warning is unnecessary.

      Your suggestions are wrong. 

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

      Ellipses are extremely commonly used in CS as a generic placeholder.

      and am thinking that a warning is unnecessary.

      The warning was indeed spurious in this case. It's there to catch the following error: 

      print (4+3)*2;   # Expected to print 14, but prints 7

        Hello ikegami,

        Interestingly, this particular warning goes away if the print command is terminated by a semicolon:

        15:54 >perl -wle "print ((1))"
print (...) interpreted as function at -e line 1.
1

15:54 >perl -wle "print ((1));"
1

        I get the same behaviour on my various Strawberry Perls, which range from 5.14.4 to 5.22.0.

        Seems to be another (strange) heuristic employed by the warnings pragma.

        Update: Changed wording of first paragraph (underlined words) to clarify that my comment applies only to cases like ikegami’s example, in which “the statement completed by the semicolon is a complete and unambiguously correct print statement” (BrowserUk, below). See also my earlier post: Re^3: false warning: print (...) interpreted as function.

        Cheers,

      It's an ellipsis.
