Why is this not working?

Tried to compile using dmd 2.066 and dmd 2.067. Code taken directly
from dlang website here (http://dlang.org/tuple.html). Thanks.
Broken documentation presumable because the feature changed later on.
The code works if you we std.typetuple.TypeTuple:
import std.stdio;
import std.typetuple;
void main()
{
alias TL = TypeTuple!(int, long, float);
foreach (i, T; TL)
writefln("TL[%d] = %s", i, typeid(T));
}
