parse-tree-il rejects '(define ...)

[Matt Wette]

This is guile 2.0.11.  

I think I’m following what is in the reference manual. 

Any clue what the problem is? — Matt

scheme@(guile-user)> (define t1 '(begin (define (toplevel x) 1)))

scheme@(guile-user)> (parse-tree-il t1)

ERROR: In procedure scm-error:
