In that case they're not essential in the *language*. I find singularly
unpersuasive arguments that we need something in the language because
it is useful to a debugger.  A useful debugger has to go beyond the
language.  For example a debugger should be able to inspect function-local
and non-exported module variables.

Yes, a debugger and the tools to build it are outside the

scope of this report.  However continuable exceptions

have many other uses, and I retract my phrasing which

may have implied they do not.
