     Wibble to fix of Trac #5439: deal with the error-recovery case

     Even if we are recovering from a typecheck error, we should still do
     the right thing for the "closed" flag.  Otherwise we get an assert
     failure, and potentially different behaviour when the user fixes
     the original type error.
