I'm very lost, now.  As best I can remember and/or reconstruct 
this conversation, the form above is adequately readable and 
does not involve lambda (and fits in eighty-column lines, and
has a few even more mundane features).  There's a realm within
Pythonia that favors lambdalessness.  

I think that's all I'm claiming at this point.
