Your proposal sacrifices constness to make this work. Are you also planning to sacrifice infallibility, or do have a solution for infallibly loading postcard data?

If you want to switch between compiled data and postcard without call-site changes, you cannot use `.unwrap_infallible()` (which is unstable anyway) at the call sites, because you have to handle...

@sffc and I agree that this can be 3.0

For categories (https://crates.io/categories) we probably want to set i18n, l10n, and no_std.

`icu_list` has a couple of invariants that are not available on `icu_pattern`, specifically that `{0}` and `{1}` have to appear in that order, and that nothing can precede the `{0}`...

- @zbraniecki - I had originally envisioned preferences as a util, but now it contains semantic data for Unicode extension keywords, so it seems fine as a component. For pattern,...
