As much as anything, I'm just tired of seeing a bunch or piecemeal
fixes.
Note that we *need* to include
from __future__ import print_function
in order to support things like
print() # Would print "()" (the repr of an empty tuple) otherwise
print(foo, end='') # Would SyntaxError
print(bar, file=sys.stderr) # Would SyntaxError
