After playing around with functional languages, I've come to envy how easy they make it to curry functions. Call a 2-argument function with 1 argument and you get a function that takes 1 argument. Pass another argument and it evaluates the function. Simple. In contrast, C++ users have to use binders, which are not as nice. On a lark, I implemented a wrapper that turns any TR1-style function object into a "curryable" function object (attached). Successive function call invocations bind arguments until enough arguments are bound to invoke the wrapped function. With it you can do the following: curryable<std::plus<int> > p; auto curried = p(1); int i = curried(2); assert(i == 3); Is there any interest in such a thing? -- Eric Niebler BoostPro Computing http://www.boostpro.com
