From doc: https://dlang.org/spec/operatoroverloading.html
Postincrement e++ and Postdecrement e-- Operators
These are not directly overloadable, but instead are rewritten
in terms of the ++e and --e prefix operators:
Postfix Operator Rewrites
op rewrite
e-- (auto t = e, --e, t)
e++ (auto t = e, ++e, t)
Rewriting part doesn't work with operator overloading.
If the rewriting part doesn't work with overloading then why
aren't we allowed to explicitly overload
```post-increment/decrement``` operators?
How else will the OP solve their problem?
It must rewrite, otherwise it's impossible (I think).
This work:
```d
import std.stdio;
struct abc{
int[100] a;
ref int opIndex(int index)return{
return a[index];
}
}
void main (){
abc s;
s[0]++;
++s[0];
}
```
