I'm thiking of interactive systems like browsers.  This problem was
found by JED/Ruby when it tried to provide interactive Ruby feature.

Let me think about it.

  * whether redefining raises an exception, or warning, or report nothing.
  * if reports some kind of error, whether it can be stopped or not.

Hmm, 5 combinations.  And if error reports can be stopped, we should
determine how to specify it.
