Well now THAT is interesting.  Same total number of calls but now
they're split exactly half _le and half _gt.

This in turn strongly suggests that the calls are the one my patch
changed in params.c, and the one currently at line 2567 in subst.c.

If we could figure out whether these two are actually examining the
length of the same array each time, there might be a way (cache in
the struct value, as with the "arr" field?) to cut this in half.
