Looks like C++ is adopting ever more D features:


"proposed a syntax for declaring preconditions, postconditions, and invariants 
for a function in its interface (i.e. in its declaration), primarily for the 
purpose of static analysis and enabling compiler optimizations."

"Bjarne presented the latest version of his proposal for automatically 
generating comparison operators for class types."

"Unified call syntax. This proposal, by Bjarne, seeks to unify the member 
(x.f(y)) and non-member (f(x, y)) call syntaxes by allowing functions of either 
kind to be invoked by syntax of either kind."

"A restricted form of static_if;"

"Extending static_assert to allow taking for the error message not just a string 
literal, but any constant expression that can be converted to a string literal."

"noexcept(auto), which basically means “deduce the noexcept-ness of this 
function from the noexcept-ness of the functions it calls." (This is essentially 
doing "nothrow" attribute inference.)

"Eric Niebler came to that meeting with a detailed and well fleshed-out design 
for ranges in the standard library."
