I'm still grappling with the possible implications of this work. Lingy, as I understand it, is being designed to be somewhat portable ... Imagine Clojure as a lingua franca alongside C with JIT-level performance to match.
Ingy also demoed a wrapper for YAML parsers which could read configs as YAMLScript. Imagining my config files becoming config middleware - This machine has 'test' in the hostname, return the test database credentials...
(Not sure how I feel about something like that just yet)
