First, the problem with a tagged union is that the size of the struct is the size of the largest union element. So for the example below, even if most objects are bool or int, the overall size will be 64 bytes, which is very memory inefficient. Therefore, tagged union technique is mostly applied where different sizes of different types are similar, or temporary objects on stack that can be freed after this call.
