No objections from me, and thanks for spotting the OpenMP thing above.

I would say, though, that this is a fairly general and subtle tool to
have around, so it would be nice to have others chime in. In other
words, do we want to start using `assume`s? Should we constrain its
use a bit, e.g. say its use should really be justified etc.? (In the
Rust side, a tool like this would require a SAFETY comment on top with
a justification, which may give a developer pause).

Thanks!

Cheers,
Miguel
