This is what is already happening today. One of the future improvements
we discussed was transitioning to a canonical format that used the
argument types, much like C++ does. But this is a big project on its
own, and we're not sure yet whether the debug info is sufficient for
this, and how much code needs to be implemented in order to match
the relevant semantic rules of the Ada language.

Just to be certain, I assume that if the user selects "all", then
we still get one multi-location breakpoint?

I am cool with that. Might be a little ugly, but I don't think
we should penalize the other languages just because we're not ready
to do so in Ada.
