Subject: "classes are always open" for anonymous classes?

So you know how classes are always open?  What about anonymous classes?

I try:

x = Class.new

class x
  def foo
  end
end

but get:

SyntaxError: compile error
(irb):2: class/module name must be CONSTANT
        from (irb):5
        from :0

I suppose class_eval is the equivalent?

x.class_eval {
  def foo
  end
}

my_x = x.new
my_x.foo

Unfortunately, that's not as clear.  I think that's something I'm going
to have to live with, but any pointers for things I'm missing?

Also, is there any reason that the "class" declaration couldn't accept
my first attempt at this ("class x; def foo; end; end")?

Thanks,
Josh
