std.concurrency doesn't like structs, classes?

I managed to solve the original problem, without using 
std.concurrency as inspiration, like I mentioned I was doing.

I have one more question regarding the original problem, but I 
posted that to .learn (by mistake, the first part of the post was 
a D / DMD issue, oops).

Still, on this topic of std.concurrency, would it be too hard to 
solve the bug, for the benefit of others?
