The ```post increment``` still doesn't work :(
this is the output for your code:
```
Proxy(7FFC7ACB3E60, 0)
2
```
And if the add the following statements:
```d
writeln(s[0]++);
writeln(s[0]);
writeln(s[0]++);
writeln(s[0]);
writeln(++s[0]);
```
Output:
```
Proxy(7FFCBE3CAF20, 0)
Proxy(7FFCBE3CAF20, 0)
Proxy(7FFCBE3CAF20, 0)
Proxy(7FFCBE3CAF20, 0)
3
```
