This should allow for compile-environment-specific reader behavior. * module/system/base/compile.scm (read-and-compile): * module/system/repl/common.scm (repl-read): Pass the environment to the language-reader. * module/system/repl/repl.scm (meta-reader, prompting-meta-read): * module/system/repl/command.scm (define-meta-command): Use the second argument to repl-reader, so we avoid frobbing current-reader.
