Cross Browser console.log implementation. I use this to be able to call log(arg1, arg2, ..., argN) in every browser.

CrossBrowserConsoleLog

  // Cross-browser support for meaningful console.log
  // @usage: log(arg1, arg2, ..., argN)
	var log = function(){

		if( console && console.log ) {

			switch( typeof console.log ){

        // Browser supports the function.
				case 'function':

					console.log.apply(console, arguments);

				break;

        // IE7 and IE8 partially support, they expose an object
        // that cannot handle .apply() or .call()
				case 'object':

					var msg = [];

					for( var i in arguments ){
						msg.push( arguments[i] );
					}

					console.log( msg.join(" ") );

				break;

			}

		} else {

      // For everything else there are some hidden divs.
			var elem           = doc.createElement('pre');
			elem.className     = 'consoleDebug';
			elem.style.cssText = 'display:none;';

			for( var i in arguments ){

				elem.innerHTML += arguments[i] + "\n";

			}

			doc.body.appendChild( elem );

		}

	}
