So after some more experimentation, it looks like define-syntax
doesn't do recursive expansions on the template replacements at all.
Is that "correct"?  If so, it seems to substantially limit the
usefulness of define-syntax/syntax-case.

(foobar) from the top level will fail with a module defined like this:

  (define-module (some module))
  (use-modules (ice-9 syncase))

  (defmacro baz () 42)

  (define-syntax foobar
    (syntax-rules ()
      ((foobar) (baz))))

  (export-syntax foobar)
