[gdb] feature request; list-processing functions

[Benoit Hudson]

It'd be nice to have something like 
    follow list member n
to do list->member->member-> ... -> member

Also, a lisp-like map operation
   map function list member n
where function is a gdb function that takes one argument (like print,
inspect, output, display, and perhaps other things that make sense).
     mapn 'print /x' list member 2
Does 
     print /x list
     print /x list->member


Is there a good way to do that now (other than write an unused function in
the source, though that doesn't help with a core dump) ?
