Interesting Research Paper on Constructors in OO Languages

[deadalnix]

My policy is to require the bare minimum to construct a valid 
object, in order to avoid initialization hell.

Not knowing what/when to initialize thing is really painful as 
well. It also introduce sequential coupling and wrongly 
initialized object tends to explode far away from their 
construction point.

What goes in this category ? Any state that can't have any 
default value that make sense, as well as any state that is 
expansive to initialize.
