Initialize array of objects not work

[Andre Pany via Digitalmars-d-learn]

Hi,

I try to initialize an array of objects. The methods 
(linear/equals/....)
returns object of different classes, but all implement a common 
interface "Element".

Element[] elements = 
quadraticCoefficient(1)~linearCoefficient(2)~equals()~constant(1);

I tried different casts and different ways but it seems, 
currently D does not support this syntax?
I always get some strange error like: Incompatible types for .... 
object.Object and object.Object.

Is there any nice way to initialize an array of objects without 
much syntax overhead?

Kind regards
André
