Yup, that's because, like Rubn said, copying value types is
trivial. Where it all comes to bite you is when you start
having pointers, because you can't copy a const(T)* into a T*.
I'm not using reference types, but still:
```
struct S {
int a;
this(int a) {
this.a = a;
}
}
void main()
{
immutable S d = 3;
}
```
onlineapp.d(10): Error: mutable method onlineapp.S.this is not
callable using a immutable object
onlineapp.d(10): Consider adding const or inout to
onlineapp.S.this
const still leaves the first error, inout works though I don't
know what it does.
Adding pure also works.
