Exercise 2.82: Show how to generalize
|
||
|
|
apply-generic to handle coercion in the general case of multiple
|
||
|
|
arguments. One strategy is to attempt to coerce all the arguments to the type
|
||
|
|
of the first argument, then to the type of the second argument, and so on.
|
||
|
|
Give an example of a situation where this strategy (and likewise the
|
||
|
|
two-argument version given above) is not sufficiently general. (Hint: Consider
|
||
|
|
the case where there are some suitable mixed-type operations present in the
|
||
|
|
table that will not be tried.)
