Thanks, that's the simplest and most effective. I reduced it to:
struct A
{
enum hasState = false;
private mixin template funDef()
{
void fun(int x) { writeln(x); }
}
static if (hasState)
mixin funDef!();
else
static mixin funDef!();
}
void main()
{
A a;
a.fun(42);
}
I see no way to extract the scaffolding into a library.
Shouldn't it as simple as a mixin-able template that simply forwards all
methods of a type T (and if it has no state it does so statically).
With __traits(allMembers,...) to extract all publics, it must be doable.
The end result should be around the following...
struct A{
//aliases type or contains state as required
mixin extractState!T;
}
