      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

        It's an ellipsis.
