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

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.
