Reflection.Emit

OK, I was interested in generating code at runtime and compiling it. Not that I really need it, I was just curious how the whole thing works.
Here is a good article on MSDN that gives a pretty decent example.
And while the concept looks pretty cool, it doesn't look like(and I sure am glad for that) that I will have a need to use this anytime soon. Maybe if I was in the business of code generation and/or compiler business I would find a good use for it, but for now I think it just is rather complicated to find a good use for it.
