Isn't what you describe (documentation first, then code) basically a poor man version of literate programming ;) ?

I wasn't familiar with the term, but a quick search reveals Literate Programming on Wikipedia [1]. I assume that is what you were referencing. I skimmed the summary of the article and it sounds interesting (and similar to what I'm describing).
