Yep.  The irb error message is actually giving a pretty good hint here.
Classes defined with the class keyword are always constants because they
start with an uppercase letter.

I suppose class_eval is the equivalent?

Right again.  You can also use that or you can assign to a constant:

  X =3D x

  class X
    def foo
      puts 'bar'
    end
  end

  y =3D x.new
  y.bar

Although, in that case, you might as well assign to the constant in the
first place; although, if you continue down that road, there's really no
point in declaring it anonymously.
