A table constructor make-table
In the table implementations above, the keys are tested for equality using
equal?
(called by
assoc).
This is not always the appropriate test. For instance, we might have a table with numeric keys in which we don't need an exact match to the number we're looking up, but only a number within some tolerance of it. Design a table constructor
make-table,
that takes as an argument a
same-key?
procedure that will be used to test ''equality'' of keys.
Make-table
should return a
dispatch
procedure that can be used to access appropriate
lookup
and
insert!
procedures for a local table.
