Predicates

getAnElementType	Gets any of the types in the union or intersection.
getAnUnderlyingType	Repeatedly unfolds unions, intersections, parentheses, and nullability/readonly modifiers and gets any of the underlying types, or this type itself if it cannot be unfolded.
getElementType	Gets the `n`th type in the union or intersection, starting at 0.
getNumElementType	Gets the number of types in the union or intersection. This is always at least two.
