This task is straightforward in the original, and if it's not too bad to cons up the name from this macro goo then I'm over all in favor.

You won't be able to set a breakpoint on a specific source line, but setting a breakpoint by name, such as "b TargetProperties::SetNonStopModeEnabled" has worked before and keeps working with this implementation. It will take you to Target.h:106 which is the shared source location for all boolean set functions.

Yeah, this isn't great, but at least it's an established pattern that's used all over our code base.

Oh! I *didn't* know that. Is there a good reason to keep these properties there or would it make sense to just build a central place for all properties.
