Now, here's an interesting question ... is there any way to get access to
the parameters of the calling context?  What I'm getting at is, it would
be much nicer if one didn't need to pass the "args" parameter to
overload() all the time.

If overload() could get access to the parameters of the single args parameter
of the method that's calling it, that would feel just a little  neater.

I know about caller(), but if memory serves correctly,  that only return
an array of strings, not the actual parameters.
