Implementation of Type Properties

[Aditya Ramesh]

Hello everyone,

I am curious as to when we can expect support for 
std::is_trivially_constructible, std::is_trivially_copy_constructible, 
std::is_trivially_move_constructible, and so on. I noticed that the 
implementations of the standard containers use the GNU C++ Type Traits 
Extensions, which do not quite have support for all of the required 
queries. I am guessing that support for these extensions requires 
cooperation from the GCC backend as well, but are there plans to 
implement them any time soon?

Thank you very much,

Aditya
