If you can initialize a field with CTFE, then you can do it directly.
Otherwise,
you have to do it with a constructor at runtime. If it's a member field of a
struct or class, then you use a normal constructor.
class C
{
this() { ... }
}
If it's a static field of a struct or class, then you use a static constructor
in
that struct or class.
class C
{
static this() { ... }
}
If it's a variable at the module level, then you use a module constructor (also
labeled with static).
static this() { ... }
