Did you actually test that?

Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> print("hello")
hello

Since print is a keyword when not imported from future, there's no way
for print(value) to be parsed as a function call.
