Note, that these manipulators are defined in the <code>tuples</code> subnamespace. 
For example:
<code><pre>cout &lt;&lt; tuples::set_open('[') &lt;&lt; tuples::set_close(']') &lt;&lt; tuples::set_delimiter(',') &lt;&lt; a; 
</code></pre>
outputs the same tuple <code>a</code> as: <code>[1.0,2,Howdy folks!]</code>
