+  - sometimes "// comments" are interleaved with "/* comments */"
+  - multiline comments should start with initial almost-blank line:
+    /*
+     * Good
+     * multiline
+     * comment
+     */
+    /* Bad
+     * multiline
+     * comment
+     */
+- resolve XXX notes where possible
+- fix FIXME notes
+- clean-up commented-out code
+- fix typos
