`make-iota-generator``count``#!optional``start``step`procedureCreates a finite generator of a sequence of

`count`numbers. The sequence begins with`start`(which defaults to 0) and increases by`step`(which defaults to 1). If both`start`and`step`are exact, it generates exact numbers; otherwise it generates inexact numbers. The exactness of`count`doesn't affect the exactness of the results.(generator->list (make-iota-generator 3 8)) ⇒ (8 9 10) (generator->list (make-iota-generator 3 8 2)) ⇒ (8 10 12)
