It would be useful to have information referred to the autoload file,
and I've wondered about how to do it, but I don't think it's trivial
with the current way line numbers work.  We would probably need to add
an extra internal variable for file line numbers, and present another
variable (or array, if in the funcstack style) to users to distinguish
the two.
