First the Function function string had no spaces or trailing semi, then did in the second half.

Perhaps a linter bot would be better, but manual will do for now.

```js run

let a = 1, b = 2;

These three mean the same:
```js
new Function('a', 'b', ' return a + b; '); // basic syntax
new Function('a,b', ' return a + b; '); // comma-separated
new Function('a , b', ' return a + b; '); // comma-separated with spaces
new Function('a', 'b', 'return a + b'); // basic syntax
new Function('a,b', 'return a + b'); // comma-separated
new Function('a , b', 'return a + b'); // comma-separated with spaces
```
Functions created with `new Function`, have `[[Environment]]` referencing the global Lexical Environment, not the outer one. Hence, they can not use outer variables. But that's actually good, because it saves us from errors. Explicit parameters passing is a much better thing architecturally and has no problems with minifiers.
