What libraries should run.dlang.io support?

[Seb]

As I just addded emsi_containers to it, I was wondering what 
other libraries would be useful for you?
(For performance reasons, a selected list of libraries is 
pre-compiled [1].)

https://github.com/dlang-tour/core/wiki/Runnable-DUB-packages 
provides an overview of what's currently supported.

I think the two coolest example atm are Vibe.d 
(https://run.dlang.io/is/gI1NA5) and mir-algorithm 
(https://run.dlang.io/is/3pNRH8).
