I'd rather NOT call them with a normal send, because that leads to the problems below.

In "new Capacity(...)", the "new" allocates the space, while the constructor body initializes the object.  This makes calls of superconstructors easy, as we just call them by name (without the "new") as I wrote in my code.  If we had to resort to calling them the same way as methods then it would somehow have to know when to allocate space and when not to.

Moreover this has the advantage of working the way that other languages they are familiar with work.

Just the way that I (and you) wrote them.  Put them in pointy brackets.

Am I missing something?
