clear to anyone and works for any string.
Well, that was my first reaction, too. But when I started to think
about it, particularly when playing around with implementing objects as
coroutines, I realised that it is nice to be able to do:
without having to know whether obj is a traditional table-based object,
or a function-based object. (In other words, the implementation of obj
could change without having to change consumers of the object.) Of
course, you could write a wrapper for obj to make it work properly, but
Mark's idea seems like a nice way of getting around having to do that.
So (I presume) it would be specifically for that case, in which case it
is not really that limited or peculiar.
