The problem is that with this change both Gst::Element and Gst::Bin will have a
[] function, which both have very different semantics. And as Gst::Bin is a
child of Gst::Element this is really not something you want. So we should
choose one and stick with it.

I know i and some others have various bits of code around that expects
Gst::Element#[] as defined in this patch. So i'd obviously like to keep that
and to get rid of Gst::Bin#[] to making porting a lot easier. And in practise
it seems more convinient too :)
