I could be mistaken, but those languages don't have the notion of 
declaration, do they? (honest question)

Last time I tried a similar language, basically, any variable 
name that is not yet used is resolved to null. Which is why the 
syntax work.

D on the other hand has a strong notion of declaration, and 
construction.

I'm not sure it's just a matter of "messy syntax", and more of 
different paradigms. In D, it is more important to make the 
distinction of construction/assignment. The syntax is messy, but 
the new syntax blurs that line.
