Subject Re: Choosing C++ version for interop.
Date Wed, 20 May 2015 07:47:31 GMT
I do not think we will sacrifice anything. C++11 has lots new features such
as smart pointers and lamdas, but I do not see where we can use them on our
public API.

For example, both Hazelcast and GigaSpaces has the following API for cache
GET:
boost::shared_ptr<MyVal> val = cache<MyKey, MyVal>.get();

Boost contributed smart poitners to C++11 and we can implement it as
follows now:
std::shared_ptr<MyVal> val = cache<MyKey, MyVal>.get();

I.e., with pure C++11 and no dependency on Boost. But in my opinion
returning smart pointer from cache GET doesn't add any value comparing to
returning unmanaged pointer, which user can wrap into smart pointer later
if he really needs it:
MyVal* val = cache<MyKey, MyVal>.get();

I think having less dependencies and greater backward compatibility
outweight features like this.
