It doesn't feel appropriate to comment there for me not knowing any Rust really, but "lax_" (or "relax_") would have the extra benefit of being very short.
(Is this going to overload operators or are people going to have to type this… a lot… ?)
Rust has some precedence for adding convenience newtypes with overloaded operators (eg. `Wrapping<I>´ for `I.wrapping_add(I)` etc). Such a wrapper isn't currently proposed AFAIK but there's no reason one couldn't be added in the future I believe.
