Re: [ns] multiple inheritance

[John Heidemann <johnh@ISI.EDU>]

But multiple interhance is a Bad Idea, regardless of what language
you're using.

You don't say WHY you want to do this, but I suggest you consider
aggregating functionality using composition.  If you look at the
current ns code, the current node structure does things this way and
BaseStationNode no longer works the way you describe it (or it
shouldn't!).  See for example the node-config command and how nodes
are constructed.
