With the master branch compiled against GCC 4.8.0 I currently get this outp=
ut:

  gdc -fdebug -O0 -g <=E2=80=A6>
  /opt/gdc/include/d/4.8.0/std/algorithm.d: In Elementfunktion

for the following code:

import std.algorithm;
import std.range;

struct Leaf
{
    ubyte symbol;
    ubyte codeLen;
}

struct CanonicalHuffman
{
    Leaf[] table;

    void print()
    {
        auto list =3D zip(iota(table.length), table.dup).array
            .sort!((a, b) =3D> a[1].symbol < b[1].symbol)
            .uniq!((a, b) =3D> (a[0] & (1 << a[1].codeLen) - 1) =3D=3D (b[0=
] & (1 <<
b[1].codeLen) - 1));
    }
}
