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?
