Maybe... but I'm mainly looking to be able to add information to 
all objects(fields) and mainly this is for debugging purposes 
because Visual D/Studio does not allow one to always get at 
certain global variables(One has to specify the fully qualified 
name and jump through a few hoops)...

But I figure it could be useful for other things too. I just 
don't see why we can't do have such a feature. I mean, if 
everything could be done with extension methods then why have 
object in the first place?
