+ I am a context for compiling methods. I maintain the namespace of classes and gobal variables that are visible to the methods compiled within me.
+ 
+ I have the following instance variables:
+ 
+ info <EnvironmentInfo>
+ Metadata about me and the code I contain
+ 
+ imports <Import>
+ Rules for importing globals from other environments
+ 
+ exports <Export>
+ Rules for exposing globals to other environments
+ 
+ declarations <IdentityDictionary>
+ Bindings for globals that have been declared inside me
+ 
+ references      <IdentityDictionary>
+ Bindings for globals that are used by methods compiled inside me.
+ 
+ public <IdentityDictionary>
+ Bindings for classes that have been declared inside me, and which satisfy
+ the export rules contain in 'exports'.
+ 
+ undeclared      <Dictionary>
+ Bindings for globals that are used by methods compiled inside me, but
+ which aren't present 'references' and couldn't be found via the rules in
+ 'imports'.!
