• #706 4045d2d Thanks @marvinhagemeister! - feat: support disposing effect() with resource management

  This allows effect()'s to be disposed with the new using keyword from the explicit resource management proposal.

  Whenever an effect goes out of scope the Symbol.dispose function is called automatically.

  const count = signal(0);
  
  function doSomething() {
  	// The `using` keyword calls dispose at the end of
  	// this function scope
  	using _ = effect(() => {
  		console.log(count.value);
  		return () => console.log("disposed");
  	});
  
  	console.log("hey");
  }
  
  doSomething();
  // Logs:
  //  0
  //  hey
  //  disposed
