Or maybe you couldn't understand because of *my* poor english or
my poor way expressing what I meant. What I meant was that, using
your example, the following:
rngfiltered(pred) is a valid expression if and only if
make_p(rng,pred)
would be what you'd be saying if you'd meant make_p to be
literally make_p instead of the p in make_p actually being
the same sequence of characters as that naming the function
on the rhs of the  operator. I know, it's a lot of nitpicking,
but I just wanted to make sure.
