teh left – giving a runtime class cast exception if it can’t do the conversion. Therefore if you know they type you are expecting you can still use it on the LHS with whatever constraints you want?<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Now don't be hasty with a JIRA. Using Comparable for the arguments of the min and max accumulate functions will give you a result that is -- Comparable. So:<br>
<br>
$min: Comparable() from accumulate( Schedule( $d: date ), min( $d ) )<br>
<br>
OK, this will give you the minimum data, bound to $min, although it won't let you write any constraint for the "Comparable" result fact. But, what's worse, it will not let you write<br>
<br>
$min: Number( intValue > 100 ) from accumulate( X( $y: y ), min( $y ) )<br>
<br>
any more (unless I'm very much mistaken).<br>

<p class="MsoNormal">Well, if it can work that way it should. I'd say open a JIRA and request that feature. It works with the "principle of least confusion." :)<o:p></o:p></p>
