7846	do_action and apply_filter should report if the user function is missing	nbachiyski	anonymous	"do_action/apply_filters tell me somehow that I the user function doesn't exists. For example I have entered the action name wrong and there is no proper way to debug it other from luck and guessing.

Fixing do_action is easy -- it can just return false or WP_Error. The problem is with apply_filters -- it's return value is dependent on the user function and we can't interfere with it in no way."	defect (bug)	closed	normal		General		normal	wontfix
