globalEval

globaleval.js

function (
    a,	//string 
    b 	//placeholder
){
    b = window,
    '' + a === a && /\S/.test(a) &&			//check the arguments(not only NUL)
    (b.execScript ||					//IE || chrome
        function() {b["eval"].call(b, a)		//fix the eval's scope
    })(a)
}

index.js

function (a,b){b=window,""+a===a&&/\S/.test(a)&&(b.execScript||function(){b.eval.call(b,a)})(a)}

I don't quite understand what is the use of /\S/.test...
By the way, you could use ''+a===a instead of typeof a === "string" to check if a is a string.
Also, if window is not the only way to represent the global object, use this or self instead.

Those skills can be learnt from https://github.com/jed/140bytes/wiki/Byte-saving-techniques

thanks tsaniel, /\S/.test used to make sure that not only NUL

I think that is superfluous, `''+a===a`` is enough to prevent NULL.
