Handling Invocation Errors
--------------------------
- generic: no-method
- method: no-method (gf <generic>) args
When an application invokes a generic function, and no methods at
all have been defined for that generic function, GOOPS calls the
`no-method' generic function. The default method calls
`goops-error' with an appropriate message.
- generic: no-applicable-method
- method: no-applicable-method (gf <generic>) args
When an application applies a generic function to a set of
arguments, and no methods have been defined for those argument
types, GOOPS calls the `no-applicable-method' generic function.
The default method calls `goops-error' with an appropriate message.
- generic: no-next-method
- method: no-next-method (gf <generic>) args
When a generic function method calls `(next-method)' to invoke the
next less specialized method for that generic function, and no less
specialized methods have been defined for the current generic
function arguments, GOOPS calls the `no-next-method' generic
function. The default method calls `goops-error' with an
appropriate message.
