> Yes, it is legal to declare and initialize a static texture (or more generally, a static variable that contains objects), like in the following shader:
Texture2D real_tex;
static Texture2D tex = real_tex;

float4 main() : sv_target
{
    return tex.Load(int3(0, 0, 0));
}

However, that particular piece of code is only active when the variable is **not** initialized, which is legal, as long it is not used before being assigned a proper object (that can be determined statically), such as in this shader:
```hlsl
Texture2D real_tex;
static Texture2D tex;

float4 main() : sv_target
{
    tex = real_tex;
    return tex.Load(int3(0, 0, 0));
}
```
