<p>The actual match type used by the parser depends on two types: the parser's 
  attribute type and the scanner type. <tt>match_result</tt> is the meta-function 
  that returns the desired match type given an attribute type and a scanner type. 
</p>
<p>Usage:</p>
<pre>    <span class=keyword>typename </span><span class=identifier>match_result</span><span class=special>&lt;</span><span class=identifier>ScannerT</span><span class=special>, </span><span class=identifier>T</span><span class=special
