I think you need to do

  (require (for-label (only-meta-in 0 typed/racket)))

as explained in the discussion thread for this bug report:

  http://bugs.racket-lang.org/query/?cmd=view%20audit-trail&database=default&pr=14068

Since this confusing error case has come up at least twice, is there
something we can do to make it less confusing? Maybe document it in
Typed Racket's docs or maybe the error message could provide more
information?

Cheers,
