You seem to be intentionally taking that Clojure code out of context. The refactored of version of that code, which compares much more favorably with your C# 3.0 version, was given as:

  (reduce (sum-field :productioncost) 0
     (filter doubleMargin?
           (map attach-liquid-value assets)))

On the contrary, I think that the C# code the author presented was unfairly IN CONTEXT. It showed using statements, a namespace, the program entry point, and other boilerplate. While I agree that C# has a non-trivial class boilerplate and non-zero function boilerplate, the Clojure you quoted doesn't even show any function boilerplate (defn foo [args] body)

I compared a C# 3 expression to a Clojure expression.

And that bit of Clojure that you quoted uses helper functions which are not defined. The C# version of that is:

  (from asset in assets
   let liquidValue = GetLiquidValue(asset)
   where DoubleMargin(asset, liquidValue)
   select liquidValue).Sum()

Clojure is a great language, but this article unfairly bashes C#, which is also a great language.
