3815	Clearing an iterator range	Daniel James	Joel de Guzman	"The attached test fails to compile with this error:
{{{
../quickbook-1.5/boost/spirit/home/support/attributes.hpp:710: error: 'class boost::iterator_range<const char*>' has no member named 'clear'
}}}
The problem is that `iterator_range` looks enough like a container so that `is_container` returns true, but it doesn't have a `clear` method. The attached patch attempts to fix this by adding a special case to clear iterator ranges.

I used a slightly odd method to clear the range, because for some reason `begin` is called for the cleared range (this may be a bug) and that's not allowed for default constructed ranges (since default constructed iterators can be singular)."
