> F# and all ML derivatives are an aberration because they use juxtaposition to denote function calls. That eliminates a lot of parens but personally I find the result less readable. It makes a lot of sense when all functions are curried. Parenthesised function calls treat all of these as different things: f(a, b, c, d) f(a, b, c)(d) f(a, b)(c, d) f(a, b)(c)(d) f(a)(b, c, d) f(a)(b, c)(d) f(a)(b)(c, d) f(a)(b)(c)(d) If functions aren't curried, then these all mean different things. When functions are curried, all of these have the same semantics (call `f` with `a`, call the result with `b`, call that result with `c` and call that result with `d`); ML's juxtaposition syntax makes these semantically-identical expressions syntactically-identical too: f a b c d
