im a bit rusty with typescript, but can these be like generic method, and then only define these verbose methods if there is something more tricky than simple assign? generic like this (this is also ugly, but just as illustration):

public map<T extends object>(source: any, targetType: IConstructor<T>): T {
    const target = this.activator(targetType)
    Object.assign(target, source);
    return target;
  }

Thanks for this, spent some time during POC trying to implement the generic method but got stuck with some dumb issue and decided to leave it for later. Applied now everywhere based on your proposal, please rereview. We can improve as we go. @skosito
