+(defmacro with-size
+  "Although normally not necessary, it is sometimes desirable to have
+  access to the size parameter when building a generator. This can be
+  achieved by the with-size combinator. The body must return a generator.
+  Example:
+  | => (with-size s (let-gen [x [Integer 0 size]] x))"
