The question is we should have weak or no distinction, or perhaps
a little strong destinction. I must admit, the code looks nice.

What about something like

   total = r | filter(f) | map(m) -> accumulate(zero, a);

or

   total = r | filter(f) | map(m) >> accumulate(zero, a);

?

The is a problem when we just want to apply several algorithms:

  boost::erase( cont, boost::unique( boost::sort(cont) ) );

How do we express this? Perhaps

  boost::erase( cont, cont >> sort >> unique );

?
