if everybody could use a macro in their editor or IDE, it's a strong hint that the language could do better.

(looking at you, java)

I have debated this. I was actually going to formulate mine into a pre-processor so that if I can change a macro it will retro-actively update the other ones. I thought it would be useful for this, and for structs that I want to replicate for various types.

At what point are we just creating a new language that compiles to Go, though?
