He speaks to the currying syntax directly in the comments. The important distinction is that the "nice" Scala syntax for currying requires that you allow for it when you write your functions. That's not really broadly useful, though it can pretty up some applications.

From reading Odersky's book Scala's notion of currying functions i.e. f(x:Int)(y:Int) is differentiated from partially applied functions. Here is his currying example using a partially applied x():
def x(a:Int, b:Int) = a + b
val y = x(1, _:Int) // y is a partially applied function
y(2)
==========
Much better looking than his snippet:
def x(a:Int, b:Int) = a + b
def y = Function.curried(x _)(1)
y(2)
I appreciate informed criticisms like this, but he is definitely representing Scala in as poor a light as possible.
