Thought I'd offer some clarifications regarding nested classes, since I've
been using them quite heavily since early March:

1) nested classes are just like nested functions. You can declare them
pretty much wherever you can declare a variable.

2) nested classes are *not* the same as Java inner classes. The latter
include a reference to the enclosing parent, whilst the former do not. In
Java you have to know the "EnclosingClass.this.method()" incantation to
reach the method of an enclosing class (from a child). In D this simply does
not exist. Instead, you pass the enclosing class as a constructor argument
and reference it in the normal fashion. Note that many nested classes do not
need to reference the parent at all ...

3) nested classes are perfectly visible to the outside world. If you have a
nested class Bar within enclosing class Foo, a simple Foo.Bar gives you the
nested class. That is, new Foo.Bar(); is legitimate syntax. Such talk of
"super private" is both badly misguided and misleading.

4) nested classed are the business! As are nested functions. Nice work

I didn't think of that.

I forgot to mention that there's an outstanding bug related to nested static
constructors. See the bug NG for details.

Thanks Kris for such a clarification!
I think it should be placed to Wiki.

But D's nested classes are the same as Java's nested classes.
