Kawa's symbol/namespace/environment functionality was designed to support
Common Lisp packages.  See gnu.kawa.lispexpr.LispPackage.  This code is
not currently used: so it needs to be hooked up to the reader and 
appropriate
library functions.  And there are no doubt bugs and missing functionality.

Also, the property support in Environment.java is intended to support
Common Lisp property lists, but using a hash table instead.  Of course
there are complications is you want to seemlessly support fast hash
accessing *and* access the properties as a traditional list.  I had
some plans for synchronizing these, but I'd have to did a little
to figure it out.
