D in my opinion in some ways is close to these goals. It's
simpler to understand and write than C++. It has the problem of
being a GC'd language however and it's unclear to me if the GC
in D is evolving like the Go GC is. ...
The things I really want from D to really sway me would be the
following (some already exist):
1. Evolve the GC like Go has.
2. No overhead calling C libraries.

Bad news: without complete redesign of the language and turning
into one more C++/CLI (where you have different kinds of pointers
in the language for GC and non-GC), having C performance and
Go-style low-pause GC is not really possible. You have to choose
one. Go chose GC with short pauses but paid with slow speed
overall and slow C interop. D chose C-level performance but paid
for it with a slow GC.
