RE: [boost] boost::nil

For a library like Lambda, "0" has a valid meaning. Lambda uses "nil" to
mark the end of a typelist of data. The only requirement is that it must be
a unique type. For Lambda we don't have a corresponding value. Hence
"nil_pointer" is not a good choice for the name. We could change it to
"nil_tuple_item" as we don't expect users of the library to have to type it.

The name "null" would be fine too.
