There is no mistake. (But 'auto' is redundant.)

void main() {
     import std.algorithm, std.stdio;
     enum a = [ 3, 1, 2, 4, 0 ];
     enum b = sort(a);// static is not CT !!!!!
     static assert(b[0] == 0); // does not pass with static auto b...
     writeln(b);

This is worse. Now there is an allocation at runtime.

So maybe we can do a blog post on when to use static or enum? Because smart people don't seem to be agreeing on this...

Yes please! cc Mike. -- Andrei
