That's what assert does, in part. Since print is now a function, not a statement, you can do this: assert print(expression) or True to get the same effect.

So "context" is also going to be keyword? That's two new keywords, breaking twice as much existing code: anything that uses "debug", anything that uses "context". By the way, you know that Python has a read-only global variable that tells you whether you are in debug mode? You can write a function to display anything you like, and wrap it in a test like this: if __debug__: display(locals()) -- Steven
