I think it's better to make these specs more explicit. The automatic specs based on the names seem to magical for me. I think it's better to have 1.9 and 2.0 versions and loop over the names inside the spec


```
ruby_version_is "1.9" do
  it "keeps initialize and initialize_copy private when aliasing"
end

ruby_version_is "2.0" do
  it "also keeps initialize_clone, initialize_dup and respond_to_missing? private when aliasing"
end
```
