Let's say I have this code:

int x(int param) {
static int myvar = 1234;
if (param == 0) return myvar;
else { myvar = param; return myvar; }
}
}
void main()
{
X x1 = new X;
X x2 = new X;
x1.x(0).writeln;
x2.x(0).writeln;
x1.x(17).writeln;
x2.x(0).writeln;
}
```
Is there a way to make myvar local to each instance of `X`
without making it a variable of `X`? Just curious.
The only way I can think of is something like this:
```
import std.stdio;
interface X
{
int x(int param);
}
class XImpl(size_t n = 0) : X {
int x(int param) {
static int myvar = 1234;
if (param == 0) return myvar;
else { myvar = param; return myvar; }
}
}
void main()
{
X x1 = new XImpl!1;
X x2 = new XImpl!2;
x1.x(0).writeln;
x2.x(0).writeln;
x1.x(17).writeln;
x2.x(0).writeln;
}
```
Of course it's not entirely what you want but yeah I think that's
about the closest to a solution that isn't overcomplicated.
