+# $2 - the current token, also accessible by $__arg from the above scope -
+#      basically a private copy of $__arg
+# $3 - a private copy of $_start_pos, i.e. the position of the token in the
+#      command line buffer, used to add region_highlight entry (see man),
+#      because Zsh colorizes by *ranges* in command line buffer
+# $4 - a private copy of $_end_pos from the above scope
