guile/module/ice-9/syncase.scm
Andy Wingo 131826039c syncase early in boot-9, defmacros in terms of syntax-case -- halfway working
* module/ice-9/boot-9.scm
  (eval-when): Remove, as syncase is going to handle this one for us.
  (sc-expand, sc-expand3, sc-chi, install-global-transformer)
  (syntax-dispatch, syntax-error, annotation?, bound-identifier=?)
  (datum->syntax-object, free-identifier=?, generate-temporaries)
  (identifier?, syntax-object->datum, void, andmap): Oh, ugly of uglies:
  add these exciting definitions to the main environment. Hopefully we
  can pull them back out soon.
  (make-module-ref, resolve-module): Stub these out, as a replacement for
  expand-support.
  (%pre-modules-transformer): Define to sc-expand, so that we are using
  syncase from the very start.
  (defmacro, define-macro): Define in terms of syntax-case.
  (macroexpand, macroexpand-1): Remove, there should be a different way
  to get at this -- though perhaps with the same name.
  (make-module): Make sc-expand the default module-transformer.
  (process-define-module): Issue a deprecation warning when using ice-9
  syncase.
  (primitive-macro?): Remove, no meaning...
  (use-syntax): Deprecate.
  (define-private, define-public, defmacro-public): Rework in terms of
  syntax-rules.

* module/ice-9/syncase.scm: Gut, as syncase is provided by core now.
