I have a range which is the result of a couple of chained range operations, and each element is:
Tuple!(string, "product", double, "price") Now I'd like to sort the range by "price" using: sort!((pp1, pp2) => cmp(pp1.price, pp2.price) > 0)(theRange) But I get a compile time error: source/services.d(166,63): Error: template std.algorithm.sorting.sort cannot deduce function from argument types !((pp1, pp2) => cmp(pp1.price, pp2.price) > 0)(MapResult!(__lambda5, Result)), candidates are: /home/bahman/Programs/D/dmd-2.071.0/linux/bin64/../../src/phobos/std/algorithm/sorting.d(1027,1): std.algorithm.sorting.sort(alias less = "a < b", SwapStrategy ss = SwapStrategy.unstable, Range)(Range r) if ((ss == SwapStrategy.unstable && (hasSwappableElements!Range || hasAssignableElements!Range) || ss != SwapStrategy.unstable && hasAssignableElements!Range) && isRandomAccessRange!Range && hasSlicing!Range && hasLength!Range) source/services.d(168,5): Error: var has no effect in expression (theRange) dmd failed with exit code 1. And I have no clue what it is complaining about. I'd really appreciate any hint/help on this. Thanks, -- Bahman
