some_file and curfile are the same thing I guess. You can combine those
and eliminate the middle-man:

Oh my, those two were meant to be the same (sorry, I'm juggling between
the actual script and comp.unix.shell too fast). I get it, there's no way
to parse the output from a pipe into a particular argument of a function
on the right side of a pipe.

You can do that, too, if you don't line command substitution. See my
xargs example upthread. On my system (using -I to define the
placeholder)...

ls | xgawk 'NR == 3' | xargs -I{} fun {} 1 6

Thank you both for putting me on track.
