Does it matter, really? I don't remember why I marked it noexcept. There's 
no difference.

The absence of a tutorial and a design rationale are not deliberate, in the 
sense that I don't believe that the documentation is better without them. 
Lack of time is more correct.

My initial idea was that the target audience for this library consists 
largely of people who already know they need a variant type, but can't or 
don't want to use std::variant for some reason. They could make do without a 
tutorial. Or stated more diplomatically, my estimate was that they would 
prefer having the library available sooner without a tutorial than waiting 
for a tutorial that they don't need.
