1.6 Specialized arguments to generic functions

Unless otherwise stated, this manual uses the following convention for specifying which arguments to generic functions are specialized:

• If the generic function is a -setter function, the second argument is the one that is intended to be specialized.
• If the generic function is a "mapping" function (such as do-sheets), the second argument (the object that specifies what is being mapped over) is the one that is specialized. The first argument (the functional argument) is not intended to be specialized.
• Otherwise, the first argument is the one that is intended to be specialized.
