Currently doesn't work on Typed Racket

[takikawa]

Running the macro stepper on this file does not work:

#lang typed/racket
"hello world"

I've included the debugging output here: https://gist.github.com/takikawa/df6328a95a4ccd3d568a

This much smaller program has a derivation parse error as well:

#lang racket

(define-syntax (m stx)
  (syntax-case stx ()
    [(_ e) (local-expand #'e 'expression null)]))

(m 1)

This program has a parse error that looks more like the TR one:

#lang racket
(begin-for-syntax (module* m racket))

The same program but with module instead of module* has a different derivation parse error.
