Thanks! This is all I have, and I think from here on there will be more 
additions instead of big changes. There is one major change not effected 
yet, which affects both the compiler and phobos: the renaming of head, 
toe, next, and retreat to (respectively) front, back, popFront, and 
popBack. Also in foreach we will make the following change:

foreach (e; range) body

from:

for (auto copy = range; !copy.empty; copy.popFront)
{
     auto e = copy.front;
     body
}

with:

for (auto copy = range[]; !copy.empty; copy.popFront)
{
     auto e = copy.front;
     body
}

Notice the extra [] when getting the copy of the range. The reason is 
that people want to do:

foreach (e; container) {}

when the container is actually not a range. Operator [] for a range will 
simply return the range itself. For a container, it will return that 
container's preferred range.
