Declare view-specific variables on the fly with a blade directive. Use @var('variable', 'value') to use. Paste the code from this gist into a service provider.

directive.php

\Blade::directive('var', function($expression) {
    $segments = array_map(function($segment) {
        return trim($segment);
    }, explode(',', preg_replace("/[\(\)\\\"\']/", '', $expression)));

    return '<?php $' . $segments[0] . " = '" . $segments[1] . "' ?>";
});
