That's interesting, I've also read the discussion about Constructor 
Syntax in the Wiki.  While Java seems to have some holes in its 
constructor approach, I think C# has fixed these holes, or are there 
also problems with C#?

It's probably the case I've got too much Java/C++ on my brain, so I'm 
slow to embrace the new approach. I'm so use to accessing instance 
variables in constructors that it's habit now.  I would hate to see in 
the initializer conditional logic based on the way an instance is being 
constructed.  However, I don't know if the would really be a problem in 
practice.  I think I'll go take a look at past java code I've written 
and examine the non trivial constructors I've written and investigate 
the application of a Nice solution.
