This is a bug in the compiler. Change your function to not be a 
templated lambda, and it works:

```d
struct x
{
     static:
       auto a = iota(1,1000).map!((int i) => round(log(i))).take(30).array;
}
```

It can be reduced to:

```d
struct x
{
    static:
        auto a = [1,2,3].map!(i => i);       // fails
        auto b = [1,2,3].map!((int i) => i); // works
}
```

 From testing on run.dlang.io, this hasn't worked all the way back to 2.060.

There is already a bug report on this:
