Technically, not much time. It's mostly upgrading dependencies, 
and the occasional bugfix. However DLS would really need a lot 
more time to get better. I think its current state is a dead end, 
and if anything should be done with it, it's a rewrite, and not 
just maintenance.

A recent DMD release changed the default behavior of running unit 
tests, and broke the CI (integration tests aren't running 
anymore); and the deprecation of `alias get this` in Nullable 
created a number of deprecation messages on compilation that 
sends shivers down my spine (DLS abuses Nullable as an optional 
type).
