It can be easily shown that distutils.log.warn() is not completely
compatible with print. Consider the following code snippet:
from distutils.log import warn
print("hello", "world")
warn("hello", "world")
When this snippet is run, the print function executes successfully,
displaying the passed strings to the console. But warn() spits out a
TypeError; perhaps because it doesn't expect an arbitrary number of strings
passed to it.
