Why is Zig so Cool?

Custom allocators in c++ was never enjoyable nor easy. It introduces more template slop everywhere. That's one thing I really liked about eastl, it did allocators much better. But it wasn't maintained.

I don't use templates for that at all. Instead of:

    Class * object = new (...);

I do:

    Class * object;
    object = malloc (sizeof Class);
    if (nullptr == object) // ... error handling

    new (object) Class (...);

or if the constructor needs to fail:

    Class * object;
    object = malloc (sizeof Class);
    if (nullptr == object) // ... error handling

    new (object) Class ();
    if (!Class::init (object, ...)) {
        object->~Class ();
        free (object);

        // ...  other error handling
    }
