+ * enhancement: --script improvements:
+ ** errors on standard input, output, and error streams are handled and
+ cause scripts to exit silently, making them easier to use in shell
+ pipelines.
+ ** backtraces from scripts now go to standard error instead of the
+ terminal even if one is available.
+ ** --script can be an argument, causing the script to be loaded from
+ standard input.
+ * enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp
+ strings to foreign memory.
+ * enhancement: (SETF GC-LOGFILE) allows logging garbage collections to
+ a file, making it easier to understand heap dynamics.
