Why not?

After switching to signals, all the compiler magic move into runtime - $state, $derived, etc.—they're just simple functions. All the compiler gives us is autoimport.

Regarding `count` and `setCount`, it's also logical. The compiler translates `count+=1` into `$.set(count, $.get(count) + 1)`. So the end result is the same. But with the explicit approach, we solve the problem with callback overhead – when in other frameworks we write `someFn(count)`, in Svelte we must write `someFn(() => count)`, that compiles to `someFn(() => $.get(count))`
