A language over D

[Ziyaad]

Hi everyone.
My name is ziyaad.
I am new to dlang forum.
So basically I made this thread for some questions and advice 
from you guys.
So from beginning let's start
I am designing a language named zinc which will be memory safe 
similar to rust but simpler than it.
I have created 8 rules of memory safety which I will discuss if I 
got sometime.
So basically in the beginning I was thinking of using zig as 
backend for zinc because it offered lightweight compilier and 
also cross compilation and good heap things.
And in some way through internet I came across ldc which was 
second option for most lightweight compilier and somedays later I 
came to know even defer for first time was made in d and more 
research of d found that d is powerhouse of programming languages.
But soon I came to know that d has a gc and I mistakenly thought 
that d only have gc and my choice was still zig as backend.
But few days earlier I came across D's betterc which was the 
thing I wanted but it was not over,I found the hidden power of d 
that it is only language which can directly use cpp libs without 
needing extern c which killed me.
And now I decided to use d as backend for zinc,and D's scope for 
doing RAII work.
I have few questions does I am thinking something wrong and some 
features of d will be not working in betterc mode also rather 
than CTFE & scope what are more D's powerful features that I 
don't know please list me about them
