To me, "require-and-automatically-visible" is violating the beauty of namespace. But, maybe I felt this way because I don't understand Clojure's registry or how require works.

I thought about this more, and I think I have a better understanding of why this feels strange. Clojure has one thing called "namespaces" which are clojure.lang.Namespace objects created by the ns macro. Functionally speaking they are a storage location which mostly just contain vars and references to vars in other namespaces. They are used for code organization: specifically for organizing vars and occasionally Java classes and interfaces.

Clojure also has a completely different thing called "namespaces" which are prefixes that get attached to keywords and symbols. These can interact with ns namespaces thru the reader in a handful of ways (for instance, ::double-colon keywords and symbols inside backtick forms are resolved according to the current clojure.lang.Namespace) but for the most part should be considered a di

1. pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
   Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

   Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

   -h is for host.
   -p is for port.
   -U is for username.
   -d is for database.
