Honestly speaking, I think this case is impossible to solve in
C++. I'll show my fellow students the advantages of D over C++
in next couple of weeks, and this example is pretty good. :)
:-) Good luck!

In this specific case you could do it with a macro if you don't
mind dirty

In this specific case you could do it with a macro if you don't
mind dirty macros, but you really should implement the const
version explicitly or
Let's use an example:
import std.stdio;
class Visitor {
public:
void visit(inout A) {
writeln("visit A");
}
void visit(inout B) {
writeln("visit B");
}
}
class A {
public:
void accept(Visitor v) inout {
v.visit(this);
}
}
class B : A {

C++ has a non-idiomatic language culture. There are many ways to
do it. One clean way could be to use a templated method, another
way

Of course on real case body is much bigger and complex than
that.

The only way I found is to move the body of function inside a
mixin template:
