Well, at least a SyntaxError makes it easy to find. And even if you don't intend to use 2to3, you can still run it once to generate a patch for you that only fixes up "print". In many cases, that will also make it work in Py2 in such an "imperfect" way, either by doing the right thing already or by printing out a tuple instead of a space separated string. If it's only for debug output (which, as I said, would better be served by the logging module), I can't see why that would be all that unacceptable.
