So, please tell us : - how do you implement reflection without either ugly macros or a precompiler? - how do you implement metaclasses without a meraobject ?

So, please tell us : - how do you implement reflection without either ugly macros or a precompiler? - how do you implement metaclasses without a meraobject ?
