<p>There is a detailed and customizable protocol involved in the process of
|
|
invoking a generic function — i.e., in the process of deciding which
|
|
of the generic function’s methods are applicable to the current
|
|
arguments, and which one of those to apply. Here is a summary diagram
|
|
of the generic functions involved.
