	const click_handler = store => {
		set_store_value(store, $store = Math.random());
	};

Error: store.set is not a function

This seems niche enough that we should probably just check the scope at compile time and throw an exception, rather than getting this to work by renaming variables so that we can refer to the store.set in the top-level scope.

In 3.24.0, this is now a compiler error - https://svelte.dev/repl/8b351c8352044772a0561cc56a5f85a2?version=3.24.0
