The [`cron`](https://pkg.go.dev/github.com/robfig/cron/v3#hdr-Intervals) lib in golang has an implementation.

It is also OK to return an `ETag` header. Without either `Last-Modified` or `ETag`, it is difficult for us to ensure that the content is unchanged.

Any blockers for the stabilization of the `lazy_cell` in std?

Any progress on this feature?

Since we already have [`inspect()`](https://doc.rust-lang.org/nightly/std/iter/trait.Iterator.html#method.inspect) for an iterator, it is consistent to keep `inspect` as the `Some` version.

Any progress on the `i18n` support?

Any progress on moving this to the standard library?
