In my experience, it is an issue. dub lint does not warn about 
unused imports or unused constants, for example.

I also don't use an IDE, unless you consider nvim an IDE. And I 
don't use dub to build my code (I'm open to it, but I've found 
the documentation thoroughly inadequate), so using its lint to 
check my code is more than a bit of a pain.

So for me, the D existing tools to statically evaluate code in a 
manner similar to the Rust compiler are just not where I would 
like them to be.
