I definitely think refactoring is another aspect (no pun intended) that
would need to be included. Thanks for reminding me of it.
I wouldn't compare refactoring with adding aspects, though, given the
former is not about adding functionality and, at least in my context, the
But maybe I'm overstating the value of AOP for a project like this. I
guess I'm more generally thinking of distinctly called-out additions (and
deletions) to various points of code with the purpose of adding a single
unit of functionality. In some cases you could indicate in advance where
those points are but in many cases not.
The key is that at one point you need to say that a particular class has
certain methods and later on in the literate program you need to say
you've added some methods and added (or removed) particular code. This is
where I suspect current literate programming systems fall down for this
kind of project. For something like what I'm talking about one would need
the ability to indicate an insertion, deletion or (at the very least) a
replacement with perhaps the weaving including a code diff in the
