Lisp/CLOS provides parts of that in the function-call model.
In Lisp/CLOS the function is being assembled based on the arguments. That's called 'computing the method combination'. If there this is not possible, because there are no methods defined for these argument types, the generic function NO-APPLICABLE-METHOD gets called with the the original function and the arguments - for NO-APPLICABLE-METHOD, the user can write methods.
