Abdulaziz Ghuloum f4fb08adba Added an experimental macro expansion stack trace that looks like:
Unhandled exception:
 Condition components:
    1. &who: let
    2. &message: "not an identifier"
    3. &syntax:
        form: (let ((12 a)) (printf "a=~s\n" a)) 
        subform: 12
    4. &trace: #<syntax (let ((12 a)) (printf "a=~s\n" a))>
    5. &trace: #<syntax (right 12 a (printf "a=~s\n" a))> 
    6. &trace: #<syntax (wrong a 12 (printf "a=~s\n" a)) [byte 216 of test.ss]>


For a file containing:

(define-syntax right
  (syntax-rules ()
    [(_ a b c) (let ([a b]) c)]))
 
(define-syntax wrong
  (syntax-rules ()
    [(_ a b c) (right b a c)]))

(right x 17 (wrong a 12 (printf "a=~s\n" a)))
