Regarding the layout method lookup, the documentation states that it

Hi,
You probably misunderstood the task.

You had to create the class *BlankCellTestCase* (not BlankCell) which is a
subclass of *TestCase*.
BlankCell and BlankCellTestCase are two different classes.

It makes a lot of sense what you said, and it's a great aid in learning to
not only solve a given problem but also to do it with style and in a better

Well here is again, the refactored version.
The idea is to have a class to calculate quadratic equations.
This second draft still only calculates real roots (leaving aside imaginary
roots).
But thanks to Damien Cassou I think it has a better style.

Hi Martin,
yes, most list-like widgets can drag and drop. Feedback when inserting
items in lists could be improved, however (i.e. you can drop on a list
item, but I've never seen the feedback for dropping between list items).

Hi Nacho,
I wouldn't throw an error because otherwise one must know beforehand that an
equation is non-resolvable or must use #on:do: everywhere.
Since that when you ask to resolve an equation you get back a collection of
solutions, a non-resolvable equation could just return an empty

Yes, and if there are no solution, you get an empty set instead of an error
