why this way around? Why not

whatever( h, filter(g, transform(f, r) )

which I don't find much worse than the operator| notation, and it works consistently with anything that expects functions, boost::bind, boost::function, whatever other people have already implemented that invokes operator(). I agree with Rogier that I don't see why ranges are so different from doubles, say, that would warrant introducing a new syntax.

And wouldn't concepts in C++0x allow augmenting Ranges with things that can be invoked method-style, like
