this is the second most sought after trace (the first beeing the return 
values of the called function).
would it not be a good idea to have these 2 as predefined functions(*) 
in the dbg module? i realise that it is possible to ask for very many 
predefined functions since the mathc-spec can do anything, but some are 
more interesting than others.

(*) dbg:ctlr( Module, Function, []) would give the return trace of 
dbg:tpl( Module, Function, [{'_', [], [{return_trace}]}])

Those were the days...
