Got that! Thanks for the info!

And can't you do that with inline asm?

That's really interesting to hear! Do we have any cases where

You really shouldn't expect dmd to inline *anything*.
Or to optimize anything for that matter. That isn't its
strength.
Oh yeah! I just thought to ask anyway! Thanks a lot for your time!

Yes, this is still the case.
