`Void` and `()` cannot be used

Elements Elements Bugs

IDE: Visual Studio X/Fire
Version: 10.0.0.2459 (develop)
Target (If relevant): Island(OSX)
Description:
The compiler emits various errors for use of Void and () that are incorrect.
Although all of these cases are trivial, the compiler shouldn’t forbid them.

Expected Behavior:
Compiles.
Actual Behavior:
See below.
Steps:

let x: () = () // E62 Type mismatch, cannot assign "<tuple literal>" to "Void"

let y: Void = () // E503 Tuples require .NET v4.0

let z = () // E503 Tuples require .NET v4.0

let w: () // E96 Internal type "Void" cannot be used directly

func foo(x: () ) { // E96 Internal type "Void" cannot be used directly
    
}

foo(x: ()) // E503 Tuples require .NET v4.0

func bar(x: Void ) {
    
}

bar(x: ()) // E503 Tuples require .NET v4.0

This case is still not working on 10.0.0.2461 (develop), FYI.

func foo(x: () ) {} // E96 Internal type "Void" cannot be used directly

ah yes. Fixed.

Another, somewhat silly, Void problem in 10.0.0.2465 (develop):

var v: Void {
	return // E467 Cannot return without a value
}

Found in a test verifying properties had the correct name when translated to LLVM.

Odd. Will log.

This last thing was, unfortunately, not actually fixed in 10.0.0.2471 (develop).
It just changed the error. It now outputs:

var v: Void {
	return // E524 Method reaches end without returning a value
}
