No, because I need it to work for chunks I didn't load. Essentially, I
need to support this:

some user code
startdebugger()
more code
run-time error here

For those cases where I start the script myself (and have full control
over the context/environment), I already handle the errors. However in
most cases the starting point is controlled by the user, hence the
request.
