Hi, i neither like it nor dislike it - it just caught me by 
surprise because i was under the impression that if i create a 
new instance then all members get initialized according to the 
declared optional default value.

I can see how this is a feature - but it is also of kind "expert 
knowledge" and i would argue that "expert knowladge" is a designs 
arch enemy.
