Functional programming C++ template library

This is awesome. Maybe the successor to C++ will be C++. Another really neat library is libcppa[1], which provides erlang-inspired concurrency with the actor model but also support for general functional features like pattern matching and guards.

As less haskellish approach to functional programming boost library: http://www.boost.org/doc/libs/1_55_0/libs/range/doc/html/ind... is nice. It allows me to write:

  v | filtered( [] (int i) { return i % 2 == 0;}) | transformed([] (int i) { return i * 2;})

instead of:

  vector<int> filtered;
  copy_if(begin(v), end(v), back_inserter(filtered), [](int x) { return x % 2 == 0;});
  vector<int> transformed;
  transform(begin(filtered), end(filtered),    back_inserter(transformed), [](int x) { return x * 2;});

I find this a surprisingly good explanation of the benefits of functional programming, not just a how-to guide for the library. It probably helps that I've read LYAH first however...

Does this solve the problem of operator>>= being right-associative, while Haskell's (>>=) is left-associative?

Wow, that is beautiful! Thanks.

Choking linker with lengthy symbols.... coffee time!

What happened to all of the excitement about functional programming?
