syntax sugar for conditional check

Hello, <div class=""><div class=""><br class="" /></div><div class="">I thought it would be cool to have conditional
checksyntax, which gets converted to simple check constraint syntax. </div><div class=""><br class="" /></div><div

andeasier to write without backwards boolean logic. </div><div class=""><br class="" /></div><div class="">Thank
you,</div><divclass=""><br class="" /></div></div><div class="">AJ</div><div class=""><br class="" /></div>
