Hi, In reading through the variant docs, I noticed a requirement that at least two types must be supported by the variant. Is this meant for ease of library implementation, or is this a means of protecting programmers from themselves? :-)
It may not make sense for a human programmer to instantiate a variant with one value in it, but I can picture situations where a code generator might create a variant of only one type. Handling this as a special case can be tedious -- I have had related problems in the past generating structs of zero elements in C. Even when a human programmer is involved, one might prefer the clarity of a consistent implementation style over the performance gain of special casing. These situations might be worth considering.
