Yes, it also applies to OO languages. The current SAL, frame, ...
specify the scope that is used to qualify the breakpoint / watchpoint.

I think there are two largely independant problems here:

- two level breakpoint / location table
this assumes that something like "rbreak <pattern>" just creates
multiple breakpoints (which are then broken down into locations)

- CLI operations and changes that provide greater flexability in
manipulating the breakpoint table (rdelete, renable, breakpoint groups,
...?)

and personally I'd be completly ignoring the second one for the moment.
