But what would be the point? We already know that things are not hierarchical, and that hierarchical file systems are a kludge to make it acceptably fast to search for files in computers from the 1960s.
19:36:14beachI don't see how that is related to environments (which are just mappings from names to objects). The Scheme specification does not mention what language an implementation must be written in.
