-------------------------------+--------------------------------------------
 The current implementation of environments is completely syntax-agnostic
 and also ignores the module system. It would (IMHO) make sense to use
 something like SE's (syntactic-environments) instead of the currently uses
 hash-tables, which only provide a value store.
 Actually, I think a value store for environments isn't needed at all, only
 a mapping of identifiers to the single global environment shared by all
 other code. "Fresh" environments could be created just like modules, using
 a different module-prefix.

 Additionally, mapping modules to environments (for example by something
 like "(module-environment MODULENAME)") would be a nice feature.
