Consider

function woei(someArg) { }
function caller() {
    var x = "value";
    woei(x);
}

how to get the name of the variable from the called function? In code:

function woei(someArg) {
    // magic to find out the name of the function argument variable
    console.debug(nameOfArgument);
}

prints x, not "value" (actual value of the argument) nor "someArg" parameter name in the function itself.
