Component:  unknown       |     Version:  4.7.x

--------------------------+-------------------------------------------------
 `scheme-report-environment` and `null-environment` contain some non-
 standard bindings, mainly because it was considered more convenient once
 (there is no need to do `(import chicken)` when one wants to use `begin-
 for-syntax`, for example.

 The following extra bindings are available:

 {{{
 export begin-for-syntax module require-extension require-library cond-
 expand syntax reexport import-for-syntax import
 }}}

 `import`, `reexport` and `import-for-syntax` are from the initial macro
 environment and are always available in a fresh module.

 Probably handled just by filtering out these extra bindings, but then no
 import of modules is possible. Perhaps keep the initial bindings or just
 the `import[-for-syntax]`. Dunno. Need advice.
