Nifty way to debug the interpolated templates for angularjs

debugTemplates.js

$provide.decorator("$interpolate", function($delegate){

        var interpolateWrap = function(){
            var interpolationFn = $delegate.apply(this, arguments);
            if(interpolationFn) {
                return interpolationFnWrap(interpolationFn, arguments);
            }
        };

        var interpolationFnWrap = function(interpolationFn, interpolationArgs){
            return function(){
                var result = interpolationFn.apply(this, arguments);
                var log = result ? console.log : console.warn;
                log.call(console, "interpolation of  " + interpolationArgs[0].trim(),
                    ":", result.trim());
                return result;
            };
        };

        angular.extend(interpolateWrap, $delegate);
        return interpolateWrap;

    });
