Well, I think this should be just one command, and maybe have "break"
in the CLI issue a warning (just like it does now). But that's a
relatively small change.

The instance1.function syntax handles one important Ada case, but
there's plenty of other cases; for instance, there can be an arbitrary
chain of inlining. I'm not convinced that there's any practical way to
get it right.

I've yet to see a compelling reason to break on one constructor and not
the other. Most users don't even know the difference between when each
is called.
