Hi there, please look at this. This code occur “Assertion failure: '!vthis->csym' on line 713 in file 'glue.c”:

import std.algorithm;

class Node

{

         Node _parent;

         Node[] _children;

         this()

         {

         }

         void addChild(Node child)

         {

                  _children ~= child;

         }

         void removeChild(Node child)

         {

                  _children = remove!( (i){return i == child;} )(_children); // This line crashes!

         }

@property:

         Node parent() {return _parent;}

         void parent(Node node) {_parent = node;}

         Node[] children() {return _children;}

}

I cannot understand error message..

What is the problem? Or how can I fix it?

ps> There are not enough examples for std.container :(
