Works with ```@safe``` as well
Paul was just trying to make that other answer work, you don't
have to make copy constructors ```@trusted```
Operations are needed on `other` data, that was the reason for
a `postblit` in the original case: an `int[]` data array needs
to be duplicated.
Hey, this should be good enough now:
```d
import std;
struct Foo {
this(ref inout Foo other) /*inout*/ @safe{
/*foreach(i, v; other.tupleof)
this.tupleof[i] = cast(typeof(this.tupleof[i]))v;*/
a = other.a;
b = other.b;
foreach(i, elem ;other.c)
c[i] = elem;
}
@disable this(this);
int a;
float b;
double[] c;
}
void main()@safe{
immutable Foo a;
const Foo c;
Foo b = a;//mutable b from immutable a
//writeln(typeof(b).stringof); //Output is Foo
const Foo d = c;//const d from const c
Foo e = c;//mutable e from const c
//immutable Foo f = b;//immutable f from mutable b I
don't know why this fails but const from mutable succeeds
const Foo g = b;//const g from mutable b
}
```
