How would you achieve the same effect without passing parameters to constructors? Is that an unavoidable step?

Oh yes, another way is "Dependency Injection" or "Inversion of Control".

I'm not a fan of that since it seems heavyweight and looks rather mysterious and like magic to the casual reader.

E.g. http://www.picocontainer.org/ though I think Spring etc do this too. Picocontainer seems pleasantly lightweight and simple. Relatively.
