But the above is not a function, so would FUNCNEST even apply? Default is not to limit though, so unless you set it...?? I see no mention of FUNCNEST being applied as a limit for expression recursion. That said, I'm still trying to wrap my head around how that expands. Looks like setting -x doesn't work. Hmmm....Why not?
