Re: syncase code issue 1.8.8 -> 2.0.11

[Matt Wette]

I found the root bug, I think, flagged by this message:

scheme@(guile-user)> (define-tokenizer tokiz ("[a-z]+" #\a))

While compiling _expression_:

ERROR: build-constant-store: unrecognized object #<procedure make-regexp (_ . _)>

I was putting procedure-objects in the macro when I should have been putting in syntax.

works:

  (list

   (datum->syntax (car cz) 'make-regexp)

   (string-append

    "^" (syntax->datum (car cz)))))

broken (but worked in guile 1.8.8):

   (list

    make-regexp 

    (list string-append "^" (car cz))))
