4 Working with the REPL
REPL's are one of the many great advantages of Lisp systems, allowing
for a faster development cycle. The common-module
syntax,
however, is incompatible with standard REPL usage if we want exploratory
access to imported variables because it must be entered in it's entirety
at once. Therefore we recommend REPL's to be able to provide access to
common modules somehow. When possible, that mechanism should be to
provide top-level REPL access to the following module declarations:
import-extension
import-syntax
import-lazy
