boost-phoenix

Hello all!

I can not understand what the real benefits of using Boost.Phoenix.

When I use it with Boost.Spirit grammars, it's really useful:

double_[ boost::phoenix::push_back( boost::phoenix::ref( v ), _1 ) ]

When I use it for lambda functions, it's also useful and elegant:

boost::range::for_each( my_string, if_ ( '\\' == arg1 ) [ arg1 = '/' ] );

But what are the benefits of everything else in this library? The documentation says: "Functors everywhere". I don't understand what is the good of it?
