All of Racket seems to be available while debugging GUIs. I can query
state and launch new error-free dialogs while the GUI sits there with
its broken dialog. I was thinking then that there might be some way to
change the associated contract of the offending function while the GUI
patiently waits for its next event.
Also it was type [A]...I made the mistake of calling the range of a
function like "member" "boolean?".
The goal is to enter:
(set-contract! <function> (-> ... (listof symbol?))
and carry on.

it, you're stuck.

[A] you formulated the wrong contract (the program is working but the
contract is too stringent)
[B] you program has a bug
Before you restart try to figure out which one is which and fix something.

Hello,
I'm debugging a heavily stateful GUI app that has reached a very specific state
but has come across a contract error. Is there some way to modify the contract
and proceed or I must I reevaluate and run the gui and attempt to duplicate the
state?
