Yes, this is why I went quickly over cofeescript : it is clearly 
not at all the same thin as D.

Now I think the most relevant one is scala here.

So in scala, funName is a polysemic expression : it is either the 
function or the function's result after evaluation. Scala get 
from context which one make sense.

The major difference I see with scala are :
  - You have no unary & operator to get address of. Confusion in 
that regard is completely avoided.
  - You don't have an intermediate with unexplainable type between 
a function definition and a function (like in C/C++). D try to 
work around that in a poor way. Scala totally remove that concept 
from the language, as it is a source of trouble without any 
usefulness.

The main question I ask myself is how that behavior would 
interact with other D features.
