The whole code would be too much.

This, however compiles and links perfectly well:
`
import std.algorithm;
import std.conv : to;

void main()
{
   auto res = [1, 2, 3].map!(a => a.to!string);
}
`

I use dub and `dvm use 2.071.0`. The code compiled perfectly well 
until I used `map!` I have no clue what causes it. I even used 
`dub clean`
