There is absolutely no reason to go personal. I address weak 
arguments when I see them. Liran claimed there were no benefits 
to migrating fibers. That's not true. He is speaking for his 
particular use case, that is fine. It is easy to create a 
benchmark where locking fibers to a thread is beneficial. But it 
is completely orthogonal to my most likely D use case which is in 
low-latency web-services.

There will be no data that benefits D until D is a making itself 
look like a serious contender and do it well in aggressive 
external benchmarking. You don't get the luxury to choose what 
workload D's performance is benchmarked with!

D is an underdog compared to C++/Rust/Go. That means you need to 
get that 10-20% performance edge in benchmarks to make D look 
attractive.

If you want D to succeed you need to figure out what is D's main 
selling point and make it a compiler-based feature. If it is a 
library only solution, then any language can steal your thunder...
