For the benefit of those who are joining us now, I'm pursuing a
range-based interface for Spirit (see my post on Spirit's list

For Spirit, the situation is the same. To circumvent this, I'm locally
extending the Range concept to include istreams, fstreams and, when
Range drops support for those, string literals.

To this end, there's an extensible as_range<T> class template that is
specialized to offer automatic conversion of T to a real range. Working
code is available through the link above.

What do you think of this?
