On the right track, but inside inout (or const or immutable)
constructors, the members can only be initialized once. So you
have to initialize a local, and then set the member once.
The issue is, your input is *also* inout (a necessary
condition), so you didn't declare a properly:
inout(Test!T)[] a;
foreach (mem; arr) a ~= test(mem);
this.arr = a;

Aw, thanks! This is much nicer than casting...
