How do you quote two consecutive posts?

1. >>1,2
2. >>1-2
3. >>1>>2 (faggot)
4. >other

I propose making a post quotation operator that is replaced with contents of the post it is quoting. It will be possible to compose posts in terms of other posts. Users will then be inclined to write composable posts.
It will be also very efficient to store post compositions, because instead of storing chunks of texts you can store pointers, which are much smaller.
