Buried treasure two paces south ... just what I needed! Thank you.

I saw that pop its head up while testing. I think the original
requested name is lost by then though.

I think that is what I will try. That is, when I get asked for a
function I don't know (and if I decide it can be supported) I will
create a new function object wrapping a generic call and return it in
the get. If I add it to the object, it can get invoked "normally" next
time. And hopefully argv[-2] will see me though.

Thanks
