Yeah, that sounds good, thanks!

[ I am not sure about the "without evaluating them". While the Rust
reference talks about "evaluation" in the `if` expressions page, a
`const` block there may or may not still get evaluated anyway.

  In practice, I can see e.g. the build being stopped with a const
assert at least in some cases. ]
