Ahh..META II [1]. This is awesome. Was just mentioned again in the "Joe Armstrong interviewing Alan Kay" talk [2][3]. One of Alan's favourite papers. Joe: "Dan said if you look at this, you will lose a month of your life. And I did" Or words to that effect.<p>Also the basis for OMeta[4]. I have to admit I've been avoiding it so far in order not to get diverted from architectural insights[5] but this may just be accessible enough to dive on in.<p>[1] <a href="http://www.ibm-1401.info/Meta-II-schorre.pdf" rel="nofollow">http://www.ibm-1401.info/Meta-II-schorre.pdf</a><p>[2] <a href="https://www.youtube.com/watch?v=fhOHn9TClXY" rel="nofollow">https://www.youtube.com/watch?v=fhOHn9TClXY</a><p>[3] <a href="https://news.ycombinator.com/item?id=13033299" rel="nofollow">https://news.ycombinator.com/item?id=13033299</a><p>[4] <a href="http://www.tinlizzie.org/ometa/" rel="nofollow">http://www.tinlizzie.org/ometa/</a><p>[5] <a href="http://objective.st" rel="nofollow">http://objective.st</a>
