I'd advocate the strategy that we should try to have a large enough behavioural overlap that modules can be written to run on both. Subtle changes in semantics make this difficult. To the extent that this is unavoidable (
e.g. behaviour of very core syntax) I guess we'll have to live with it. But we can easily add a function called textfile() to both Python 2.x and Python 3.x and ease the transition.<br></div><br> Paul Prescod<br><br></div>
