Compiler should warn on output file collisions

1

`src/foo.ts` and `src/foo.lua` will both become `out/foo.lua`. We should emit warnings in cases like this. For Windows, paths are case insensitive! This means that: - `src/Foo.lua` -> `out/Foo.lua` - `src/foo.ts`...

`LuaTuple<T>` can be double wrapped if passed through a generic function

3

This code results in the `LuaTuple` value being wrapped in a table twice, which is incorrect. ```TS function foo(value: T): T { return value; } function returnsLuaTuple(): LuaTuple { return...

And ideally any other place where this pops up. [playground link](https://roblox-ts.com/playground/#code/A4JwlgdgLgFAflEBXApgSiA)

 ...I had forgotten about this. Our current fix is to just apply parentheses to the RHS of a `luau.BinaryExpression` where the current and parent operator precendences are equal. [Which...

Right now, we put every macro input into it's own temporary variable in the order they're passed into the function call. This is good for ensuring execution order, but looks...

`LuaTuple<T>` cannot be spread into a fixed arg length function call

2

```TS const components = new CFrame().GetComponents(); // error TS2556: A spread argument must either have a tuple type or be passed to a rest parameter. const cframe = new CFrame(...components);...

If a user defines `src/foo.ts` and `src/foo.lua`, both files will write to `out/foo.lua`. We can't do much to "fix" this, but we should probably error in this case. Incremental mode...
