I am a newbie myself (second week of learning Haskell), but I'll give it a shot: Since functions have no side effects, the compiler executes the function only once.

Sure, "pure" programming languages *allow* the compiler to perform such optimizations but it does not mean it is *actually* done (promises are cheap but writing compiler code is expensive).
