Episode 72: Erik Meijer on LINQ

This episode is a discussion with Erik Meijer on LINQ. This is a
relatively technical discussion about the following topics: what is
LINQ, what are the common abstractions between the different data
structures one can access with LINQ, what is the relationship to
established languages for querying, how does the integration into
the type system of the host language work, how to specify the
mapping between the language level classes and the data, and how
optimizations are implemented (lazy loading, prefetching, etc.).
