Subject: Difference in module_eval taking block vs. taking string (1.8 bug?)

The following code:

class Klass
end
p Klass.instance_methods(false)
Klass.module_eval do
    def hello
       puts 'hello'
    end
end
p Klass.instance_methods(false)
Klass.module_eval("def hello2() puts 'hello2'; end")
p Klass.instance_methods(false)

produces this output in 1.8.0pre3:

[]
[]
["hello2"]

but in 1.6.8 it produces:

[]
["hello"]
["hello2", "hello"]

Is this a bug in 1.8 or a feature?
