Today starts a new series I'm calling Snippets and it's about various D-specific stuff that may come in handy when building a GUI. You can find it right here: https://gtkdcoding.com/2020/03/23/0105-dlang-ui-snippets-i.html |

If it's enough with CTFE compatible code in the constructor, the following is a much simpler version:
class DSingleton
{
private __gshared DSingleton instance = new DSingleton;
DSingleton get()
{
return instance;
}
}

Or if an immutable instance work, the getter is not necessary and the instance can be exposed directly.
class DSingleton
{
immutable DSingleton instance = new DSingleton;
}

Should of course be `static`:
class DSingleton
{
static immutable DSingleton instance = new DSingleton;
}

Thanks, Jacob. I can't take credit for the Singleton code, though. I stole it from here: https://wiki.dlang.org/Low-Lock_Singleton_Pattern |
