The observant reader may notice there is no procedure for creating a point. This is because a point is just a pair whose car and cdr both evaluate to #t when passed to the number? predicate. All that is required to create a point is to cons two numbers together. Note: it is possible to use any type which returns #t for the number? predicate in a pair, however the author only plans to support integers, rationals, and real at this time. The option is left for the adventurous to use other numeric types at their own risk.
