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.
