- errors that are typical of "Python 2 script running with Python 3"-specific are probably limited (e.g., use of unicode, use of xrange, etc...) The most common, in interactive scripts at least, is likely to be:

print "Hello, world!" SyntaxError: invalid syntax How helpful it's possible to make that one, I don't know. Is it safe to presume that it's more likely a syntax error will come from an interpreter version mismatch than a code bug? The wrapper in /usr/bin/python: - could use what is in 2to3. I think that most of the cases are solved there. - whenever interactive, could have an intermediate layer between the input in the console and execution.

So you suggest that instead of a clear SyntaxError you should end up with a confusing error (something has no attribute xyz or so) after a while (if say somone tries to load twisted via 2to3).
