DMD 2.059beta (not head), on a 64-bit GNU/Linux

---------------->8---------------->8----------------
import std.typecons;
import std.stdio;

void main() {
  alias Tuple!(int, long, float) TL;
  foreach (i, T; TL)
    writefln("TL[%d] = ", i, typeid(T));
}
----------------8<----------------8<----------------

I get:
_field_field_0
Internal error: e2ir.c 688

source (under the section 'Looping'):
http://dlang.org/tuple.html

The code in that section is also wrong and doesn't compile.  The following
gives the correct output:

---------------->8---------------->8----------------
import std.typecons;
import std.typetuple;
import std.stdio;


void main() {
  Tuple!(int, long, float) TL;
  foreach (i, T; TL)
    writefln("TL[%d] = %s", i, typeid(T));

  alias TypeTuple!(3, 7L, 6.8) ET;
  foreach (i, E; ET)
    writefln("ET[%d] = %s", i, E);
