Environment and module

[Manuel Giraud]

Hi, I have some question about environments and modules in guile :

        - Is the environment structure still a draft proposal as it is
          said in
          http://www.gnu.ai.mit.edu/software/guile/docs/env.html
          because I'm not able to find anything in guile 1.4;

        - How do I create and use my own guile module ? Can I "close"
          a module and return to the previous bindings and syntaxes ?

        - A finally more general question : What is, for you guys, the
          best documentation for guile (source excepted) ?
