Someone's blog recently reminded me about Intentional Programming (IP) - thanks, whoever you were!
I'm pretty certain that IP died a death at MSR around 2001 - shame :-(
See here for an old Microsoft Research video on what this 'was' all about.
However, let's not give up all hope just yet - IP may still become a reality someday! I sure hope/pray that it does - it's a wonderful concept!
