Yes, you can already achieve what this feature can do by other means,
but this feature makes these cases 1) more efficient in terms of how
much work has to be done 2) simpler and more elegant to write. But
frankly I find it a bit insulting that I shouldn't work on this based
on other people's priorities. This is a high priority item for me.
I'll look at the problem reported by Amit and come back with a
solution and my rationale for adding this feature.
