Hook for ignored errors?

[Andrew Gierth <andrew@...>]

The current 5.4 releases assume that the only useful thing that can be
done with an ignored error is to emit it as a warning if it is a string,
and emit a generic message otherwise.

Would it not make sense to provide for a more specific "I'm about to
ignore this error object" function that the environment can supply, that
allows any kind of value and not just strings?
