In order to make `%map` available to the enum transformer, it needs to
be defined at expansion time, e.g. (this is one way, there may be others):

    (begin-for-syntax
      (define-syntax %map
        (syntax.rules () ...)))

Also note that because `enum` is an ir transformer, the form provided to
it will already have been renamed, so as it stands it will most likely
define something like "my-foo123" rather than "my-foo" -- you'll
probably have to `inject` those parts of the form in order to have the
correct identifiers bound as a result </possibly unwelcome observation>.

Cheers,

Evan
