D is totally useless

[Temtaime]

I'm new in D, so i'm tried to write some in that langugage.
That's story about how i tried to port OGL sample, that renders 
one triangle.

I was very surprised when i found, that D doesn't have equivalent 
of gl/gl.h. Any C++ compiler has it.

Okay, i'm investigate in it and found OpenGL in deimos.
It doesn't support a lot of OGL function such as glPushMatrix and 
others.

Okay, then i found derelict3. It has a lot of OGl functions and 
it's okay.
When i tried to rewrite example to D, i was shocked.

core.sys.windows.windows doesn't have a lot of functions. It 
doesn't contain simple function DestroyWindow for example.
It's intresting, but go ahead, i found derelict.util.wintypes 
with missing functions. I've got a lot of "conflicts with" 
errors, because some of functions was in derelict's wintypes too. 
I've solved it. When i tried to link my program, i've got a lot 
of "undefined reference" errors. Okay, i've built and link 
derelict libraries. Then errors became stranger:
DerelictUtil.lib(traits)  Offset 204C4H Record Type 0091
  Error 1: Previous Definition Different : _D67 
DMD\windows\bin\..\..\src\phobos\std\traits.d.17012__ModuleInfoZ

So i can't to rewrite simple OpenGL example that consists of 50 
lines.
This example works on every C++ compiler without building/finding 
any libraries.

Dlang's standard windows.h heade is useless, because a lot of 
functions/structs definitions is missing.

Dlang is a toy in outer space.
One can only to write a+b program in schools on it.

Now i'm understand, that's why D doesn't have popularity after 
10+ years of existence.
