:mrdocs:

Return the index in the list of `TYPES` corresponding to the type of the value currently held by this variant object (starting at 1), or 0 if this object is unset. Note that instead of switching code on the type index, calling `apply` is the preferred method of manipulating different types stored inside a variant.
