A stack overflow is something I might want to catch within pcall(), is
what I am saying.  Someone a day ago in #lua told me that there is a
limit on the recursion depth of C function calls, or something like
it.  I wasn't happy about that because I was trying to port something
I saw in javascript so I could find the maximum recursion depth before
stack overflow.  I wouldn't do it with __index, but infinite loops are
sometimes desired is all I am saying.  I wouldn't limit something
because I think others might not want that ~
