It's almost a "yeah". However this doesn't work with ref
parameters. Any idea how to make this work, keeping the
simplicity of the concept ?

module runnable;
import std.stdio;
struct Foo
{
void delegate(int) event1;
void delegate(int,int) event2;
void delegate(int,ref int) event3;
}
struct Handler
{
void handle(A...)(A a){writeln(a);}
void handleref(A...)(/*auto ref*/ A a){writeln(a);}
}
void main(string[] args)
{
import std.traits;
Foo foo;
Handler handler;
foo.event1 = &handler.handle!(Parameters!(foo.event1));
foo.event2 = &handler.handle!(Parameters!(foo.event2));
foo.event3 = &handler.handleref!(Parameters!(foo.event2)); //
?
}
