Then go watch this video:
I was invited to the University of Minnesota today for a brief talk by Eric Van Wyk who presented over lunch about some of his research on extensible language tools. I was very surprised to find out that the research he has been doing is very similar to what I have been doing with meta#, they are working on ways to compose language extensions and create domain specific languages on top of general purpose languages. The details are different and some of them are very interesting and require further investigation but I am surprised by how much is not different.
Also, similar to the PPL and maybe even more so, he has a treasure trove of research papers on DSLs that I will have to read through.
You should have 3 innovations per release. That way if one fails you still have 2.
