I hope this helps you . Since posting the question I have found this link which seems to indicate the Slime and clisp integration is not quite working as it should be. So, in the meantime I have installed Steel Bank Common Lisp (sbcl), as easy as (on Ubuntu/Debian) code :
sudo apt-get install sbcl
;;; Lisp (SLIME) interaction
;;(setq inferior-lisp-program "clisp")
(setq inferior-lisp-program "sbcl")

zero initialization and static initialization of local scope static variable
By : kraigrs

I wish did fix the issue. I read several posts on C++ initialization from Google, some of which direct me here on StackOverflow. The concepts I picked from those posts are as follows: code :
int const i = 5; // constant initialization
int const j = foo(); // dynamic initialization

Java - Default Initialization of static variables before Static initialization

will help you You are right. Static fields and initializers are indeed executed in their declared order : code :
static {
System.out.println(Test.a); // prints 0 -> default value for `int`
a = 99; // a get 99
System.out.println(Test.a); // prints 99 -> value after previous statement executed
}

Hope that helps One needs a bit of space in memory. Const do not - they can be hard coded.

Initialization of static member with same type as class (static initialization order problem)

it should still fix some issue Based on your comments, I did the following: made constructors constexpr made static members constexpr inline (you have to put them into the header file, not the .cpp), so C++17 is needed code :
class Super
{
public:
constexpr Super(const double a):
m_a(a)
{}
double a() const { return m_a; }
static const Super thing;
private:
double m_a;
};
constexpr inline Super Super::thing = Super(1.0);
class Sub : public Super
{
public:
constexpr Sub(const double a):
Super(a)
{}
constexpr explicit Sub(const Super& obj):
Super(obj)
{}
static const Sub thing;
};
constexpr inline Sub Sub::thing = Sub(Super::thing);
#include <iostream>
int main()
{
Super super = Super::thing;
std::cout << super.a() << std::endl;
Sub sub = Sub::thing;
std::cout << sub.a() << std::endl;
}
