From my two previous questions, it seems that i learned of using :source %, @", and other trick to execute vimscript.

But as i noticed, :source % need the file to be saved first, furthermore, @" and any other trick using register don't always work.

Not needing to save first to execute something is very important for debugging/testing your code (as I'm sure many are already aware).

So is there truly no ways to execute vimscript (without as much restriction as using registers have) without saving first?
