in this case you can just use:

Ahh, great! :-)
But that directly gets me to the next question:
import std.stdio;
void main()
{
Point[] q = [Point(1),Point(3),Point(2)];
import std.algorithm.searching: minElement;
writeln(q.minElement!(a=>a.x).x);
}
struct Point
{
@property immutable long x;
}
This doesn't compile:
/usr/include/dmd/phobos/std/algorithm/searching.d(1365): Error:
cannot modify struct extremeElement Point with immutable members
/usr/include/dmd/phobos/std/algorithm/searching.d(1307): Error:
template instance `test.main.extremum!(__lambda1, "a < b",
Point[], Point)` error instantiating
/usr/include/dmd/phobos/std/algorithm/searching.d(3445):
instantiated from here: extremum!(__lambda1, "a < b", Point[])
test.d(8): instantiated from here: minElement!((a) =>
a.x, Point[])
Any idea, how to get around this?
