(apologies in advance if this posts multiple times, I messed up the sending email address the first time).
Hi, Trying to compile : import std.stdio, std.range, std.algorithm; void main() { auto a = [2.0,1.0,3.0]; struct Point { double x; } auto b = [Point(4.0), Point(5.0), Point(6.0)]; topN!("a[0] < b[0]")(zip(a,b),1); //sort!("a[0] < b[0]")(zip(a,b)); writeln(a,b); } std/algorithm.d(8225): Error: template std.algorithm.swap does not match any function template declaration. Swapping out topN with sort works just fine. I assume both sort and topN use swap, is there a reason this doesn't work with topN?
