There is no "new pipe operator" in the standard (as far as I'm aware).
The pipe operator is the normal, existing pipe operator from the days
of C++98.

There are overloads of this operator for ranges, but they don't
magically create syntax. They're just regular operator overloading.
And operator overloading can't make "each(x, x*x)" behave in any way
differently from how it would work on its own.
