> It seems similar to Haskell, except with parentheses That's the point: In Haskell, the parentheses (and especially the comma) are meaningful, and "foo(x, y)" is not the same as "foo x y". Reason jumps through extra hoops to make the two syntaxes mean the same thing. To a Haskell (or OCaml, or other ML family) programmer, the Reason syntax suggests an uncurried function.
