Hi Xavier,
The short answer is, no, this is not possible. Augeas cannot currently memorize a string is has met (except in the case of square lenses). In general, Augeas' goal is not to model the meaning of the configuration file, but rather the form of it. In the same way, there is no way to interpret "include" statements, you just map them. Interpreting such things should be done in the code using Augeas (through XPath expressions), not in the lens itself.
