DSL stands for Domain Specific Language. In our story, the DSL is HTML. An internal DSL refers to the host programming language’s ability to express that DSL using just the host language (with no string building). One could argue that Internal DSLs are not really a separate technique from #2 (Tree Building) and #3 (Templates). In fact, internal DSLs could be described as a less-crappy tree building API. Or as a templating language that is more integral to the host language. But I think the technique is different enough to deserve it’s own category. This person is describing Lisp, and I'm flummoxed that they do not appear to be aware of Lisp, given that it is an area where it is so strong! I think both Arc and Closure have the ability to describe HTML documents in lists (I can't remember if it's as s-expressions, or lists of functions). EDIT: I just noticed that they reference Om :) Never mind!
