rewrite-generation

[Function]
  `(``rewrite-generation` pattern [fresh]`)`

Returns an entire generation from a rewrite pattern as a list. If fresh is true then the generation is first rewritten before it is returned, otherwise the pattern's existing generation is returned. The default value of fresh is false.

#### Examples:

Example 1. Returning successive generations from a rewrite pattern.

    (define pat1
      (new rewrite :of '((a :-> (a b)) (b :-> c) (c :-> a))))

    (rewrite-generation pat1)
    ⇒ (a)
    (rewrite-generation pat1 #t)
    ⇒ (a b)
    (rewrite-generation pat1 #t)
    ⇒ (a b c)
    (rewrite-generation pat1 #t)
    ⇒ (a b c a)
    (rewrite-generation pat1 #t)
    ⇒ (a b c a a b)
    (rewrite-generation pat1 #t)
    ⇒ (a b c a a b a b c)
    (rewrite-generation pat1)
    ⇒ (a b c a a b a b c)
