Yet, the wiki page:

says:
a tag field explicitly indicates which one is in use.
and I don't see any indication of a tag field in the
std_variant.html
I remember a while back asking about the variant. I wanted to be
able to specify an area in memory and say 'this is xxx', but
couldn't; This was to help avoid having to manually make and
manage something like 60 structs and far more complex code to
manage that.
This leads me to develop my own version (for built-in types); My
version isn't anywhere complete (or clean enough) for
publication, but enough for my own project (as read-only use).
Hmmm curiously enough, i might be able to convert/rebuild by
using a polymorphic struct that I'm tinkering with, but that
seems like a lot of extra work.
