is right to left, but reversing u would be left to right.

That is unfortunate. Normally, I am perfectly comfortable with [ and @
to do function composition, but sometimes I really wish to convey the idea
of a sequence,
and it just doesn't feel like the same thing as function composition to me.
(So I prefer newlines to [ or @ in these situations, but then that wastes
vertical space...)
How would you feel about introducing, say,
`:_1 (and perhaps `:1 ) that guaranteed a left-to-right (and right-to-left)
order, explicitly?
`:1 would just be (|.m)`:_1
`:1 would just be an alias for the current implementation,
which would not change alongside `:0 if `:0 changes in the future.
