2to3 will not report this.
My meaning was the use of 2to3's machinery (and fire a message if a
translation occurs) not 2to3 itself, obviously.
It will get rid of the SyntaxError (which
at least is fairly clear) and give you a completely different and even
more obscure error. You have replaced a somewhat unclear error with a
very unclear error.
If we want to report a problem, then /usr/bin/python should just
report that you should use /usr/bin/python2 or /usr/bin/python3.
That's clear.
