Really,
I don't think new syntax is needed for that, as it is trivially resolved
by a function call
(I would type an example but Ricky's answer covers it)
Moreover, such a callable, or other helper-callables
can trivially enable ways of connecting the piped
values through specific (positional/named) parameters
in the next calls - allowing a whole Graph of functions
to be composed.
(And it is so easy to do and flexible extendable, I can't see a place for
that
in the stdlib)
