He's talking about Domain Specific Languages, in which the language is
designed to be a way to unambigiously describe some problem.

For example, SQL -- it's not terribly good at being Turing complete, but
it's fantasticly good at describing what you want to search for in a
relational set of data.

Likewise, Xpath is great way of talking about nodes in a Document Object
Model.

Doing either of these in programming-language-of-choice is possible, but
more tedious than using the DSL directly and translating the results.
