Subject: Re: [hwloc-devel] SWIG bindings

This looks great! Probably much better than SWIG-based bindings that I would have come up with.

One question: is there any value in having the $topology be a hash of public values instead of using the hwloc_get_obj_data() method? I ask because in all the perl scripty-foo that I've written that parses "lstopo -.xml", having the entire data structure available as a big hash has turned out to be quite useful, particularly on some heterogeneous development machines where the hwloc accessor functions can be misleading, or may require more logic than just trawling the data tree directly.
