Re: [boost] [core] Determining interest for two new classes: readonlyand newtype

Hey, I have two classes I've developed that have been used in my own projects that I think could have a place in Boost. They are outlined below.

readonly<T>:

This is a wrapper class for a type to replace a const-type field in a movable class. It has const access to the type so can't modify except for the move constructor and move assignment operator.

...

newtype<N, T>

This is shamelessly ripped off from Haskell and provides strongly-typed typedefs to C++.

These look interesting and useful. I do not think they belong in [core] though, which is for components that are used throughout Boost. [utility] seems a better place.
