Thanks a lot for those pointers, I changed/upgraded my dependencies, and it already looks better.

resources are freed and not rely on the garbage collector. For
that I am using reference counters courtesy of autoptr.
e.g.
```d
alias Texture = IntrusivePtr!TextureData; // dub package autoptr
class TextureData
{
IFImage image; // dub package imagefmt
}
```
another class of mine now is supposed to hold several of those
textures for multitexturing and should be initialized in its
constructor:
```d
class Appearance
{
Texture[] textures;
this(Texture[] textures)
{
this.textures = textures;
}
}
```
Unfortunately this does not work properly together with
autoptr's (see
https://github.com/submada/autoptr/issues/5#issuecomment-997683868).
Because of that I am using now DynamicArrays from Emsi
Containers, but I am having trouble initializing them:
```d
class Apperance
{
DynamicArray!Texture textures;
this(DynamicArray!Texture textures)
{
this.textures = textures;
}
}
```
does not compile.
What would be the best way to initialize the variable?
Kind regards,
