`export-syntax', `re-export' and `re-export-syntax' into the `define-module' form. This is the recommended way of exporting bindings. * srfi-2.scm, srfi-4.scm, srfi-8.scm, srfi-9.scm, srfi-10.scm, srfi-11.scm, srfi-14.scm, srfi-16.scm: Move module the system directives `export', `export-syntax', `re-export' and `re-export-syntax' into the `define-module' form. This is the recommended way of exporting bindings. * goops.scm, goops/active-slot.scm, goops/compile.scm, goops/composite-slot.scm, goops/describe.scm, goops/dispatch.scm, goops/old-define-method.scm, goops/save.scm, goops/util.scm: Move module the system directives `export', `export-syntax', `re-export' and `re-export-syntax' into the `define-module' form. This is the recommended way of exporting bindings. * slib.scm (array-indexes): New procedure. (*features*): Extend. (Probably some of these options should be set elsewhere.) (Thanks to Aubrey Jaffer.) * and-let-star-compat.scm, and-let-star.scm, calling.scm, channel.scm, common-list.scm, debug.scm, debugger.scm, expect.scm, hcons.scm, lineio.scm, ls.scm, mapping.scm, null.scm, optargs.scm, poe.scm, popen.scm, pretty-print.scm, q.scm, r5rs.scm, rdelim.scm, regex.scm, runq.scm, safe-r5rs.scm, safe.scm, session.scm, slib.scm, streams.scm, string-fun.scm, syncase.scm, threads.scm: Move module the system directives `export', `export-syntax', `re-export' and `re-export-syntax' into the `define-module' form.
