Nikhil,
I share your concerns, but I don't want to discourage Joe from
implementing new language extensions for use in his own code.
Look at it this way. There is very little syntax defined in core/. Now
extra/ has a lot of sundry language extensions, but you should be
aware that extra/ isn't really a "standard library". A lot of stuff
there is experimental, unfinished, or extremely specialized to a
specific problem domain.
Soon I will create a new vocabulary root basis/ which will contain the
parts of extra/ which are outside of the scope of core/, but
nevertheless considered essential for modern programming (UI, HTTP
server, database, XML, ...). One of my goals for basis/ is to minimize
the number of overlapping abstractions used and streamline the code as
much as possible.
So hopefully reading the code in basis/ will be easy because it will
only use the core abstractions plus a select few others (such as fry).
The code in extra/ will remain as wild as people make it.
