noCompileErrors does not work with overloaded functions

[wegendt-bosch]

Using // XPECT noCompileErrors on an overloaded function (see below) yields an exception/error, subsequently failing the test.

Example

fn overloadingTest(x : int8) : int16 {
	return x as int16;
}

fn overloadingTest(x : uint8) : uint16 {
	return x as uint16;
}

// XPECT noCompileErrors
fn main() : void {
	// XPECT inferredType --> int16 
	let x1 = overloadingTest(10 as int8);
	
	// XPECT inferredType --> uint16
	let x2 = overloadingTest(10 as uint8);
}
