It looks like `.epochMilliseconds` should work as a Map/Set key/member in some situations, though you'll need to preserve the instant in the value in the Map case if you want to preserve the zonedata / do further operations on the Instant.

For the Set case you could use a Map{v.epochMilliseconds:v} and preserve the Instant.

Not great, but I think we all blame JS for this rather than Temporal. This could be made to work by the runtime but then polyfills would fail.

Passing Dates to a React component caused re-rendering issues in some of my applications due to Date being an object.

I had to resort to numbers (Unix time) to not have to add memoization everywhere. Seems like this will continue with Temporal. Or React-Compiler will solve this.
