// The resulting type an array literal expression is determined as follows:
// If the array literal is empty, the resulting type is an array type with the element type Undefined.
// Otherwise, if the array literal is contextually typed by a type that has a property with the numeric name ‘0’, the resulting type is a tuple type constructed from the types of the element expressions.
// Otherwise, the resulting type is an array type with an element type that is the union of the types of the element expressions.
