Traits problem

[Daniel Ribeiro Maciel]

Heya!

Ok, let me explain what I want to do:


 import std.stdio: writeln;
 
 class Foo {
     float bla() { return 0.0; }
     void foo() {}
 }
 
 void main() {
     enum string[] members = __traits(allMembers, Foo );
     foreach( member; members )
         writeln( typeid(typeof(__traits(getVirtualFunctions, Foo, member) )) );
}

Is that possible?

Best regards,
Daniel

> You need enum there, unfortunately. Also note the position of [], the lack of traits import, the qualified import from std.stdio, the void return of main, and so on.
