Hi All
<div><br></div><div>I&#39;m clutching at straws here, so this may be a complete fiction, but I seem to</div><div>recall mention of purely syntactic concept definitions as part of the now-abandoned</div><div>C++0x concept proposal. Things like hasPlus. Maybe I&#39;ve just made this up!</div>

<div><br></div><div>Does any such thing exist in boost anywhere? Maybe as a concept check or type trait?</div><div><br></div><div>Thx</div><div><br></div><div>- Rob.</div>
