Re: Something like defpackage?

I don't think defpackage makes sense. Common Lisp packages are based
on information modularity based on packages, but modern languages
tend to go with "modules" directly. R6RS has "libraries". Kawa has
"modules" which are very similar to R6RS libraries. The main difference
is that Kawa associates a module with a source file: A module has a set
of top-level names, some of which may be module-private, and some of
which may be exported. Another module (including the top-level) may
"import" bindings from other modules. You can use the Kawa require
form, or the R6RS import. Kawa's version of import is the same as R6RS's,
except it is used as a top-level declaration. Think of a Kawa module
as a "flattening" of the R6RS library form: Each module is an implicit
library form, with a slightly different syntax.
