There are some threads I have opened, or where I have written 
some posts in:

In this thread
http://forum.dlang.org/thread/50A0EEA4.7010706@webdrake.net

Joseph Rushton Wakeling suggests code like this to compile:

struct Foo(_T) {
     alias _T T;
}
void bar(FooT)(FooT foo, FooT.T x) {
}
void main() {
     Foo!int foo;
     bar(foo, 1); // line 8
}



Here I have suggested to add a lenses-like function to Phobos:

Here I have suggested a little refinement for D purity:

Here I have underlined a little design problem with opCast(bool):

In the middle of this long thread I have exchanged several 
messages with Walter:
http://forum.dlang.org/thread/k7afq6$2832$1@digitalmars.com?page=10

where I have suggested to disallow:

void main() {
     auto data = [0, 1, 2, 3];
     foreach (x; data)
         x++;
}

And replace it with this:

void main() {
     auto data = [0, 1, 2, 3];
     foreach (@copy x; data)
         writeln(++x);
}

You will find many more details in the thread, especially in this 
post of mine where I have tried to explain the situation as much 
clearly as possible:
