Description

There's been discussion previously about the complexity of the ns
macro. In particular the fact that :use causes all vars to be referred
by default is widely seen as unfortunate, and the distinction between
use and require is a source of conceptual overhead for people new to
the language.

We can't change the fact that :use refers everything by default
without breaking lots of existing code. But it would be possible to
enhance :require to support referring specified vars, leaving us free
to deprecate or otherwise discourage the use of :use.
