fixes #44

Please let me know if there is anything more to be done.

Note that i deliberately did not split the function into sub-functions. I strongly agree with what @Chrikomu said at our meeting about not leaving the scope of a new until it has been deleted if possible. If you disagree i will be happy to pick up the discussion.
