Toadstool is pattern-matching library named in the honor of Jon Harrop,
the venerated troll and spammer.

Its performance is comparable to the pattern matcher of Mark Tarver's
Qi.

Lately, a new version has been released. A major change is radically
changing the syntax of the macro to make it more Lispy based upon a
suggestion by Kevin Reid. The code:

-->--
  (toad-ecase 1 2 1
    a b a -> (values a b))
--<--

became:

-->--
  (toad-ecase (1 2 1)
    ((a b a) (values a b)))
--<--

Another major feature is the addition of the TOAD-MACROLET macro.
