What's left for 1.0?

[Samuel MV]

Ok, after reading this thread and testing some code it's obvious that I 
need to read again the D documentation, and after that, read it again ;-)

Probably, for most of us, there are lots of hidden little gems in D ... 
and the docs need some update and/or extension to show this properly. 
Maybe for v1.0 we could organize a collaborative project for 'The D 
Tutorial' ...

        Samuel.
