If I had seen somebody write the above on some random webpage, I'd 
dismiss him out of hand as a kook.  But D is actually looking like it 
might reach that goal!

So I asked myself: are there any other common programming models that D 
doesn't have?  And it struck me: most interpreted languages have duck 
typing and hold-any-value variables.  Is there space for that in D?
