1. I believe D's GC is not a problem, D always say itself is `a 
systems programming language`, C#/Java/GO never say they are `a 
systems programming language`, they target users who don't care 
about GC.

No one will write an OS or "application on RTOS" by a GC lang.

In my option D should pointing to application developers like 
GUI/Web Server.

for GUI D can easily use exist C legacy, for web server it can 
improve their speed, "faster java" or "improved go".

2. Other problem for D is tools.

I tried code-d, the debugger never work for me, no rename/find 
reference in LSP. Others language like Go/Rust their LSP and 
vscode plugins is official maintained, but for D code-d looks 
like "WebFreak001" personally work.
