Is there a block undo in VIM?

In Vim, is there a way to开发者_JS百科 select a block of text and use undo to only undo changes to that block of text?

Let's say I rewrite a function, then go and make some changes elsewhere in my file. Afterwards, I realize that my first function implementation was indeed better. I'd like to undo the changes I made in that function, but leave my subsequent additions intact.

I don't know if this is even possible, but I often find myself wanting this feature.

Currently... No. Vim 7.3 has undo branches that you can traverse but as far as I know Vim does not pay attention to any selected text during an undo.

Maybe this:
