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())
