What do you mean by that?

Something like this? Or?

```d
module main;

import a!5;

void main()
{
	auto foo = new Foo;
	foo.field4 = 10;
}
```

```d
module a(int fieldCount);

import std.string : format;

class Foo
{
	static foreach (i; 0 .. fieldCount)
	{
		mixin(format("int field%d", i));
	}
}
```
