Description

remove-advice is the function used to remove a piece of advice. Advice is a way of altering the behavior of functions. Pieces of advice are associated with a function using defadvice. They define additional actions to be performed when the function is invoked, or alternative code to be performed instead of the function, which may or may not access the original definition. As well as being attached to ordinary functions, advice may be attached to methods and to macros (in this case it is in fact associated with the macro's expansion function).

hcl:delete-advice is a macro, identical in effect to remove-advice, except that you do not need to quote the arguments.

Notes

remove-advice is an extension to Common Lisp.
