So, here is another feature that D wins over C++.
Looks like C++ is adopting ever more D features:
And they seem to almost have CTFE(!)
From wiki on C++14:
C++11 introduced the concept of a constexpr-declared function; a
function which could be executed at compile time. Their return values
could be consumed by operations that require constant expressions, such
as an integer template argument. However, C++11 constexpr functions
could only contain a single expression that is returned (as well as
static_asserts and a small number of other declarations).
C++14 relaxes these restrictions. Constexpr-declared functions may now
contain the following:[5]
Any declarations except:
static or thread_local variables.
Variable declarations without initializers.
The conditional branching statements if and switch.
All looping statements, including range-based for.
Expressions which change the value of an object if the lifetime of
that object began within the constant expression function. This includes
calls to any non-const constexpr-declared non-static member functions.
goto statements are forbidden in C++14 relaxed constexpr-declared functions.
