 Building the json egg results in:

 {{{
 Error: (json.scm:109) - toplevel definition of `white' in non-toplevel
 context
 }}}

 The code looks like this:

 {{{
       (define parser
         (packrat-parser (begin
                           (define (white results) ...
 }}}

 Changing the `begin` to `let ()` results in another, more obscure error.
 Apparently the proper treatment of `define` inside `begin` inside `let`
 is not correctly expanded (`packrat-parser` seems to expand into a let
 body).
