Crazy things I somehow managed to get past Rich's review and into @svelte.dev core this year: - Introduced the first yield* into the svelte core - Introduced a variable called `pickled_awaits` that makes me happy every time I see it Stay tuned for whatever other ridiculous things I can get in

Can’t add whimsy then takes self to seriously

In case you didn’t know, generators are slow: github.com/lit/lit/pull... github.com/withastro/as...

@scriptraccoon.dev

Elliott Johnson

In general. In most “application level” use cases you won’t notice it, but you definitely do if you’re using them in a hot loop

Elliott Johnson

Yeah, for this use case it doesn’t really matter

2c but I’m surprised that it doesn’t matter for a framework that tries to squeeze performance wherever it can
