An accidental input typo when the domain EXPR is traced caused BIND stack overflow. Correcting the typo does not return the system to expected behavior.

   There are 10 exposed and 4 unexposed library operations named eval

      Use HyperDoc Browse, or issue
                              )display op eval
      to learn more about the available operations. Perhaps
      package-calling the operation or using coercions on the arguments
      will allow you to apply the operation.

      Perhaps you should use "@" to indicate the required return type,
      or "$" to specify which version of the function you need.

Unfortunately, it is currently impossible to )tr EXPR )ma, a bind stack overflow results always. Somehow, an infinite loop is created - probably for the output routines...
