In the Ruby bundle there is a “Toggle ‘do … end’ / ‘{ … 
}’” command bound to ⌃{ which does something very similar, so for 
the implementation you can look at this command.

Though I took a quick look, and it seems surprisingly complex, and it 
even reads the selection or document (when there is no selection) in 
TextMate’s XML format (which include scope info). I am not sure why 
this is necessary.

For actually overloading return and backspace in these locations, this 
is possible if you make the grammar match them and assign a scope at the 
desired locations, but I think it would be better with a toggle key like 
the Ruby bundle.

Come to think of it, there is also _Fold/Unfold Code_ in the C bundle 
(also bound to ⌃{) which also does something similar.
