Simple JavaScript string tokenizer

A crude String.Format equivalent in JavaScript -blatantly copied from frogsbrain

//from http://frogsbrain.wordpress.com/2007/04/28/javascript-stringformat-method/ 
String.format = function(text) { 
    if (arguments.length > 1) { 
        for (var i = 0; i < arguments.length - 1; i++) { 
            text = text.replace(new RegExp("\\{" + i + "\\}", "gi"), arguments[i + 1]); 
        } 
    } 
    return text; 
}; 

#twitcode version (130 characters!)

strf=function(t){a=arguments;if(a.length>1)for(i=0;i<a.length-1;i++)t=t.replace(new RegExp("\\{"+i+"\\}","gi"),a[i+1]);return t};
