If you know a name of the function you want to advice, you can make it known to the piece of advice too, of course ;-) But no, there is no special mechanism for finding the name of the advised function from within the advice code AFAIK - apart from looking at the `backtrace-frame's or other brutal things. AFAICT the process of installing advises only touches functions, but doesn't cause changes on the symbol level apart from the functions fbound to them. Michael.
