Phobos is essentially dead/frozen (feature-wise). Though if 
someone ever manages to get v2 of the ground, SumType would be 
the obvious choice.

Anyhow, currently we would have to name it differently (e.g. dts 
- https://github.com/wilzbach/dts). Maybe the upcoming SAoC 
project will change this and allow multiple versions of a library 
to co-exist in a binary.
