That is, propagate_const<Source, Target> will only add const to Target if Source is const too.

For the Numeric_Bindings library (under development) we're using an identical mechanism called copy_const. I would welcome such an addition to the type traits library.

I too have needed and created propogate const (actually propogate const and/or volatile). I'd definitely appreciate such an addition to Boost.TypeTraits. -- -Matt Calabrese
