Thanks for taking the time to share pointers to other papers! If there is one thing I like better than a post linking to a paper I want to read, its a post linking to a paper I want to read and with comments linking to other related work.
Worth pointing out that "Lightweight Modular Staging: A Pragmatic Approach to Runtime Code Generation and Compiled DSLs" is also co-authored by Martin Odersky of Scala fame. Definitely looks like good stuff.
