[Haskell-cafe] Lambda abstraction analogous to imperative pseudo-code?

The Wikipedia article on lambda abstractions (http://en.wikipedia.org/wiki/Lambda_abstraction) has a statement that does not resonate with me: A lambda abstraction is to a functional programming http://en.wikipedia.org/wiki/Functional_programming language such as Scheme http://en.wikipedia.org/wiki/Scheme_programming_language what pseudo-code http://en.wikipedia.org/wiki/Pseudo-code is to an imperative programming http://en.wikipedia.org/wiki/Imperative_programming language. Does anyone else find this to be a peculiar statement? If you think it is accurate, could you provide an alternate explanation and/or example to the one in the article?
