Is something like this what you had in mind?
```
void main() {
import std.stdio;
mixin template A() {
int I1;
int I2;
char X;
}
struct B {
mixin A;
int Var1;
int Var2;
}
B someObject;
writeln(someObject.I1);
writeln(someObject.I2);
}
```
More like
```
B someObject;
writeln(someObject.Var1);
writeln(someObject.Var2);
```
In the areas where B is used, don't want I1 or I2 to be
visible.
If you don't want members of A to be visible in B, why are you
even including struct A as part of B?
Why wouldn't you use a class and make the members private?
I'm certainly not a D expert and I don't know your use case
so maybe I'm missing something.
scot
Basically, B corresponds to the whole record (and only a whole
record can be read).
But the task only requires Var1 and Var2, the last two fields on
the record.
By putting all the irrelevant fields into A, and defining B as
above,
program remains unpolluted with data it does not need.
