Cool. Ideas: Visitor could be Loki's own - if Loki's visitor is ever
added to boost, it would be a nice example of internal reuse. Then, as
a complement to 'any' or, dare I say, maybe even a replacement, maybe
later we'd add Variant (search "Discriminated Unions" with google) to

If anyone's interested, I have a series on discriminated unions going
right now on I will soon discuss unbounded discriminated
unions, which are a particular case, and which do what 'any' does (and
more), within a larger framework.
