Cannot access 'variableName' before initialization...

[MarkTanashchuk]

In this REPL:
https://svelte.dev/repl/0cf61fcb843c47b7a9ba4bd6d6a891f7?version=3.31.0

this code:

let someData = {
  Home: "HomeData",
  // ...
};
$: currentData = someData["NotHome"] || "DefaultData";

let myText = "Bugged ;("
function fetch() {
  if(currentData != "DefaultData") console.log(myText)
};
fetch();

compiles into this code, where currentData declared after fetch():

let someData = { Home: "HomeData" }; // ...
function fetch() {
  if (currentData != "DefaultData") console.log(myText);
}
fetch();
let currentData;
$: currentData = someData["NotHome"] || "DefaultData";

And leads to an error `Cannot access 'currentData' before initialization'

Here's another example:

	import store from "./store";
	let name = 'world';
	
	$: theValue = $store;
	
	let numbersSeen = {
		[theValue]: true
	}

REPL: https://svelte.dev/repl/1753fac08700444985259933d4b58518?version=3.31.0

That code's obviously foolish and silly - the goal is to do something with that initial, original value of "theValue" which, in this circumstance, leads to a ReferenceError

This is fixed in 3.31.1 - https://svelte.dev/repl/0cf61fcb843c47b7a9ba4bd6d6a891f7?version=3.31.1
