[issue19585] Frame annotation

[Nick Coghlan]

Nick Coghlan added the comment:

Another use case from frame annotations: allowing greenlets and threads to indicate which greenlet or thread a traceback is from whenever it is printed (this is similar to the way the runtime indicates which thread a traceback occurred in when it terminates the the thread, but would apply whenever the uppermost frame is displayed in a thread that isn't the main thread, or in the case of greenlets, the uppermost frame in the greenlet, always)
