This function allows to get fully qualified name of the calling function. I expected this field to be available from logging module, but it is not here http://docs.python.org/2/library/logging.html#logrecord-attributes It might be that it is too expensive for performance or just doesn't play well in some situations. I don't know. I use it solely when debugging and it is convenient.

Nice! Do you mind if I integrate something based on your work above into circuits (1) ?

No problem. It is in public domain - use as you wish. =)
