The specification (the one available above under 'Documentation', 
can be simply be 'annotated', and therefore serve more that just 
'folks like compiler writers'.

Those who don't need the annotations, can just ignore the 
annotations.

I'm not talking 'tutorials' here, just some extra, helpful 
explanation.

The C# Programming Language, 4th Edition, by Anders Hejlsberg (et 
al) is still one of my favourite all time books (because of the 
mix of specification and expert annotations).
