It's not a signal to 99% of the humans that will read it because almost no one gets what /o does. There's just the "Oh! Optimized! Ok, it's more better n' good!"

It is faster to avoid doing the concatenation and string comparison work than not but those are cheap operations. If you were optimizing for that then you could just as well pass in a qr// object.
