I think 'add_const' is reserved for Boost.TypeTraits.

I post this tiny proposal to Boost.Devel anyway.

When we discussed the wg21 proposal many months ago and I added const_begin() etc to boost.range, Dave Abrahams used this function template< class T > inline T const& as_const( T const& r ) { return r; } Similarly, we might add as_volatile(); as_const_volatile(); as_mutable(); The latter would be a cast from rvalue to lvalue like it happens in boost.foreach. -Thorsten
