This examples is on the std.algorithm doc page:

uint hashFun(string) { ... expensive computation ... }
string[] array = ...;
// Sort strings by hash, slow
sort!("hashFun(a) < hashFun(b)")(array);
// Sort strings by hash, fast (only computes arr.length hashes):
schwartzSort!(hashFun, "a < b")(array);

As we all know, *naryFun can't access local symbols, so this example does not
compile.
