First, Ruby doesn't have UFCS. You can add a new method to any existing 
class but it's still not UFCS in the same way as D.

Second, optional parentheses in Ruby is simple due to not being in 
conflict with other syntaxes. In Ruby there are no public instance 
variables, they're always private. If you access something with the dot 
operator in Ruby, you're always calling a method.

There is not conflict with callable objects. In Ruby invoking a callable 
object uses a different syntax from invoking a method. A callable object 
is invoked using "obj.call()", or in Ruby 1.9 "obj.()".
