Ain't Nothing But a G# Thing
I came across this blog post about G# and thought it was a typo at first.
G# is an Aspect Oriented Programming (as opposed to Object-Oriented programming) language designed by Ernie Booth with the ability to generate type-safe code. I get the impression that the language doesn't really exist yet and that the specifications were just posted online.
It's not every day you get to comment on the specifications for a new language, so don't be shy: read the specs and make comments.
