Currently the docs of std.algorithm.map say: >Multiple functions can be passed to map. In that case, the element type of map > is a tuple containing one element for each function.< But lot of time ago I have said that in my opinion that's not the best design. Python has a different design, its map does what you want, you may write your code in Python as: map(myNaryFun, range1, range2, ...) An example (Python 2.6): >>> a = ["a", "b", "c", "d"] >>> b = [1, 2, 3, 4] >>> map(lambda c,n: c * n, a, b) ['a', 'bb', 'ccc', 'dddd'] Is is possible to change the std.algorithm.map to a semantics similar to the Python one, that I think is more useful?
