While I'm familiar with neither Scala nor Haskell, that seems a bad 
idea.  What happened to the idea of using a, for example, Ferrari 
interface on a Car instance?  Sure, the object is a Car, but that Ferrari 
interface is used, well, not for convenience per se, but as a reminder 
that this Car is not *just* a Car.

You're suggestion is completely contrary to that principle.  While I 
appreciate that it's easier, I don't get the point.

That being said, in Ruby you instantiate with:

foo = Bar.new

which is quite nice and simple.
