Initial Windows experience

[Peter Alexander]

I just want to highlight 
https://github.com/vibe-d/vibe.d/issues/1908 -- building default 
vibe.d example applications on win32 fails due to obscure optlink 
error. It has been like this for nearly 2 years.

I am not asking for help with this issue.

Win32 with optlink is the default build for dub on Windows, and 
given that vibe.d is the most popular D project, this could very 
well be among the first things that a D newcomer tries. If I were 
new to D, I'd likely just give up there and assume the language 
and tooling are immature.

The thread over there says that lld is shipped now with DMD. Is 
there any reason not to move to that and move away from optlink? 
It seems unnecessary to maintain and debug a separate linker when 
another more mature linker is available, working, and already 
bundled. Are there any reasons to stick with optlink as the 
default?
