I'm sure I join many in being glad there's finally a powerful language tied tightly to a mainstream GUI/Database/Communication framework. I haven't been sure where to post this, but here seems the best spot. I need to use Unicode symbol characters either as operators or as function names. I'd like syntactic sugar, but I don't need it. Guy Steele pointed out in Communications of the ACM that "*" was a forced choice when it was adopted from Ascii as multiply, but my software works in Unicode, so I'm not tethered to Ascii anymore. !$%&*+-./<=>?,@^|~: Part of localization includes local programmers. Why limit the set of operators that can be defined in F#? It isn’t orthogonal to C#'s and F#'s acceptance of many Unicode IsLetter in identifiers. Also, F# is likely to be used for symbolic manipulation of problems from logic, math, physicists, etc. It makes work much easier if there’s a direct mapping into the language of the basic operators. (F# and C# accept many Unicode IsLetter? as well as IsDigit’? This is a request to allow Unicode IsSymbol? As operators with the precedence of, for example, *, or, since “+” is both a unary and binary operator, I could put up with the precedence of + and make up the difference with parenthesized groupings. Consider the domain-specific needs of logicians, mathematicians, physicists, etc. I’d rather write a symbolic differentiator or integrator using math symbols than Ascii permutations of already-taken operators. Logic: ∀ ∃ ⇒ Math: ∑ ∫ ∂ Group theory: ≤ ≥ ∈ ∉ Set Theory: ⊆ ⊇ ⊃ ∪ ∩ Tensors: ⊗ I’ve written many languages in other languages, but because F# is tightly .Net-integrated, this issue poses special challenges without language support: It’s trivial to cobble up a translator that takes Unicode-operator F# source and maps it, line-by-line, to Ascii-operator F# source. But when d
