digitalmars.D.learn - TransitiveBaseTypeTuple doesn't seemed to print the symbols as well.

I expect ["__ctor", "__dtor", "toString", "toHash", "opCmp",

"opEquals", "Monitor", "factory"]
Care anyone explain why it is?

Source is the following:

import std.stdio;
import std.traits;

interface A
{
}


class D : A
{
     this()
     {
     }
     ~this()
     {
     }
}




void main()
{
     alias TL = TransitiveBaseTypeTuple!D;
     for(int x = 0; x < TL.length; x++)
     {
       auto b = [__traits(allMembers, TL[0])];
       writeln(b);
     }
}

Simple mistake there...

I noticed, can't fix it cause it won't let me edit it. This auto b = [__traits(allMembers, TL[0])]; is meant to be auto b = [__traits(allMembers, TL[x])];

OK, I'd just use foreach there anyway tho (then it actually builds!). But, hopefully once you get it running, you'll see that the base type tuple just gives the bases: it will print two lines, one for the base class Object and one for your interface A. Neither of them have constructors! It won't print the class D itself....

You know a equivalent template that does that?

No, though you could just AliasSeq!(D, TransitiveBaseTypeTuple!D) and make it yourself. Though note that __traits(allMembers, D) already includes all members, including those from base classes too, so you might just want to use that.
