To be honest, I'm not really sure that the summary is really what Flame wants, in fact, I'm not even sure that what zie wants currently exists. The problem is that stuff changes all the time, and keeping a document up to date with what has changed would be Hard Work (and if it's to be definitive it'd need a fair amount of time from Larry & Co to proofread it and make sure it's accurate, and really we want them working on Apocalypses.)

However, the perl6-documentation people are plugging away at producing detailed documentation which covers the 'nailed down' behaviour. So far they've produced a document on numeric literals and are working on the string literals doc at the moment.
