Debug break on variable change?

I see how to set a conditional breakpoint on a particular line of code, but is there a way to set a breakpoint whenever a variable changes (or when it equals a particular value) anywhere in the code?

Unfortunately the debugger does not support stopping when a variable changes. You can sometimes workaround this by using a property and setting a breakpoint in the set method.

I wonder if you guys could implement that functionality automatically? That would be a cool feature.

It is on our list of possible improvements. At one point (long ago now) we contributed a patch to Python to make it easier. I think it never made it into the language, but there may be comparable changes in recent Python versions. It's not really feasible to do in a general way without some language support since checking for a value change with each byte code would add extraordinary overhead.
