AFAIK the only reason Java has that "feature" is its complete inability 
to have functions *outside* of classes :).

Though I could see uses for this, like to run unittests (similarly to 
what running Python modules "stand-alone" often does).
D has gone another way there though, using explicit unittest {} blocks. 
Unfortunately, there is currently no way to run these separately (esp. 
right after compilation) that I know of.
