As Leonid mentions in one of his answers one of the methods of managing complexity is using Domain Specific Languages (DSLs). In this answer I will provide links to documents, packages, blog posts, and discussions of creating and utilizing DSLs in Mathematica.

• Just designing a DSL can bring clarity of what signatures should be in the API.

• NIntegrate's Method option was designed and implemented using a DSL. See this video between 25:00 and 27:30.

• See this answer of the discussion "Writing functions with “Method” options".

1. This answer to the question "How to parse a clojure expression?" provides two concise examples of programming and/or generating parsers for a small grammar.

2. A small part, from 17:30 to 21:00, of the WTC 2012 "Spatial Access Methods and Route Finding" presentation shows a DSL for points of interest queries.

3. The answer of the MSE question "CSS Selectors for Symbolic XML" uses FunctionalParsers.m.
