* module/ice-9/boot-9.scm (make-fresh-user-module): New public function, makes an anonymous beautified module. * module/language/objcode/spec.scm: We used to have some things in here that allowed lexical variable names and values to be a part of the environment, but no more. Now an environment is just a module. If you want to "inject" free variables into code, just use lambda. * module/language/scheme/compile-tree-il.scm (compile-tree-il): Same here. Also, rely on the fact that an environment *will* be a module -- because (system base compile) guarantees that for us. * module/language/scheme/spec.scm (scheme): In the reader, rely on the environment being a module. Define a #:make-default-environment handler, which returns a beautified module, augmented with a fresh definition for current-reader, so that side effects to current-reader are restricted to the compilation unit. * module/language/tree-il/analyze.scm (report-possibly-unbound-variables): * module/language/tree-il/compile-glil.scm (compile-glil): * module/language/tree-il/optimize.scm (optimize!): The environment will be a module. * module/system/base/language.scm (<language>): New field, `make-default-environment'. Defaults to `make-fresh-user-module'. (default-environment): New accessor, returns a default environment for a language. * module/system/repl/common.scm (repl-compile): Always compile relative to the current module, because a module is always acceptable as an environment. * module/system/base/compile.scm (compile-file, compile-and-load): Both of these have a new keyword argument, #:env. For `compile-file', it defaults to the default environment of the source language, and for `compile-and-load', to the current module. (read-and-compile): If there are no expressions read, pass the joiner its default environment (via `default-environment joint').
