Boo is an interesting, extremely flexible CLR language with an “open compiler architecture” – which means that you can easily extend its compiler to accommodate your needs. I bought a Manning Early Access Program (unfinished, unedited, and rough around the edges) book by Ayende Rahien called Building Domain Specific Languages in Boo that, despite the writing style, which conveys an accent and is so informal that it almost borders on the insane, has already proven quite useful. The book relies on an open source library, also by Ayende Rahien (of Rhino Mocks fame) called Rhino DSL. The library itself is small, simple and effective. In addition to DSL’s, Boo (which is a statically typed, compiled language) has an optional interpreter and seems like it could be effectively used as a runtime scripting language, in addition of course to being a full blown .NET language you could write your business objects or UI in.
Anyway, below are a few resources I have come across while researching this topic in support of creating a state machine DSL referenced in my previous post:

[…] class inside an in-memory assembly, and then execute the code. This is the approach you would take if you were going to use Boo (or some expression language based on Boo), but really there is a lot of baggage that comes with […]
