For the lame example I gave, something similar occurred to me

some performance penalty.
As those are templates I don't think you'd have any overhead ; I
may be wrong about that but the whole point of such constructs is
to allow what Walter poetically called “memory disallocation”.

True. But is pumping the output of `filter` as the seed into
`reduce` really considered weird usage!?
I don't think it is really weird per se, I just can't think of a
case where there isn't a better way to do it. I find it
completely unreadable frankly, and I generally avoid reduce when
I can because it is not UFCS-able. This is only personal opinion
though.
