If you have an array of structs, such as...struct Foo { int x; int y; } Foo[] foos;...and you wanted to sort the foos then you'd do something like...foos.sort!(a.x < b.x),..and, of course, both of the fields x and y get sorted together.If you have a so-called struct of arrays, or an equivalent situation, such as... int[] fooX; int[] fooY; ...is there a simple way to sort fooX and fooY "together"/coherently (keyed on, say, fooX), using the standard lib?
std.range.zip(fooX, fooY).sort!((a, b) => a[0] < b[0]); I wasn't sure if that's supposed to work. Turns out the documentation on zip [1] has this exact use case as an example. [1] http://dlang.org/phobos/std_range.html#zip
