The attached code attempts to use CRTP (Curiously Recurring Template Pattern) to see if recursive_variant can be avoided; however, I'm getting 2 variant's produced instead of 1 and the which gives the wrong result.
The attached code has test_list(void) and test_variant(void). The former has variant as super, the latter just uses a variant. The former gets wrong results, the latter correct results.
