Can someone enlighten me about the origin of the term "referential transparency"? I can lookup the definition of "referential transparency" in the functional programming sense in the Haskell Wiki and I can lookup the meaning of "reference" and "transparency" in a dictionary, but I don't know why these words were chosen as name for this defined property.
Instead of a immaculately precise definition, may I suggest going about it from the practical benefits POV? RT matters so much in Haskell because of the engineering leverage it gives us. Bird's Pearls are a good source of Why Equational Reasoning Matters.
