I found a really neat way to toggle two implementations using C style multiline comments.

Dammit, that's neat.

Favorited. That's just beautiful.

I agree.. what I see when refactoring.

Commented code: we don't use this shit anymore, but we're too lazy to delete.

#if 0: we still use this block, but we stopped it for some reason.. Please double check before deleting.
