It's not so much the compiler vs. the interpreter (though there
is a difference), but being in a module vs. not being in a module.
The interpreter loads certain units and imports them into the top level.
Once inside a module, however, nothing is available except the name
`import`, so the first order of business is to import identifiers from
scheme and chicken to bootstrap a sufficient environment to do anything.
This is equally true in the interpreter, but doesn't come up much because
most people don't type module forms to the REPL or try to execute modules
as scripts.
