[offby1]

This doesn't seem to repro now, perhaps because of changes to typed racket:

    <offby1> init typed/racket                                              [20:28]
    <rudybot> * your typed/racket sandbox is ready
    <offby1> eval  (for ([i 7]) (display i)
    <rudybot> * error: #<undefined>:1:0: read: expected a `)' to close `('
    <offby1> eval  (for ([i 7]) (display i))
    <rudybot> * ; stdout: "0123456"
    <offby1> eval (+ 3 4)                                                   [20:29]
    <rudybot> * ; Value: 7
    <rudybot> * ; stdout: "- : Integer [generalized from Positive-Index]\n"
    ERC>

Can you come up with another simple repro recipe?
