 following exceptions:
 
  * The `+=` operator wasn't added until Bash 3.1.
+
+    * As a work-around, use
+      <code>array[${#array[*]}]=<var>word</var></code> to append a
+      single element.

  * Accessing subset arrays of the arguments array is inconsistent if
    <var>pos</var>=0 in <code>${@:<var>pos</var>:<var>len</var>}</code>.
