syntax-case returns identifier even it's not macro expansion phase

[Takashi Kato]

This should return symbol but identifier.

(import (rnrs))

(define (match lis)
  (syntax-case lis ()
    ((a b c) #'a)
    (_ 'ng)))

(match '(a b c))

[Takashi Kato]

First check if the macro expansion is done during macro expansion phase (Fixes #165)
