Example:
import
std.stdio,
std.algorithm,
std.array,
std.conv
;
ulong factorial(ulong n) =>
n>1 ? factorial(n-1)*n : 1
;
T[] sorted(T)(T[] xs) =>
xs.length == 0 ? [] :
xs[1..$].filter!(x=> x < xs[0]).array.sorted ~
xs[0..1] ~
xs[1..$].filter!(x=> x >= xs[0]).array.sorted
;
void main() =>
[5,6,7,2,3].sorted.map!(i=>i.to!ulong.factorial).writeln
;
