digitalmars.D.bugs - BUG: Assertion failure

 Assertion failure: 'ident' on line 611 in file 'dsymbol.c'

interface INode { INode owner(); } class BasicNode : INode { INode findNode() { foreach(INode c; m_children) if (c.owner != this) continue; return null; } INode[] m_children; } The result is exactly the same if the owner() function is implemented in the BasicNode class.

 interface INode
 {
 	INode		owner();
 }


 class BasicNode : INode
 {
 	INode findNode()
 	{
 		foreach(INode c; m_children)
 			if (c.owner != this) continue;
 		return null;
 	}
 	
 	INode[]	m_children;
 }

 The result is exactly the same if the owner() function is implemented in
 the BasicNode class.

I was under the impression that the identifier token === (and its negative !==) were replaced by 'is' (and !(foo is bar))

Not replaced. They're alternatives. Anyway it was not a typo in the code so the '=' versus '==' versus '===' problem doesn't apply here ;) Anyways, why hasn't the 'a aint b' operator been adopted instead of '!(a is b)' ? Maybe I should add it to my preprocessor :)

Shouldn't that be "isnt" ? (since "isn't" is a keyword nightmare) I'm not really sure that D needs any more english operators, though... (and there are plenty before that one: "unless", "and", "or", "not") --anders
