Hum, don't you think that this is dangerous? A library that extends the
syntax of the language is more than a library is the usual sense. In my
mind a library is more like an API. Don't you think that enabling 
libraries to extend the syntax implies that we should agree *first* on 
the module and the macros. This is an endemic problem...

But you are creating a core-language that is not "stand-alone". Don't you
think that this approach minimizes the interest of having two stratum?
