[hibernate-dev] Hibernate.getImplementation(Object)

[Emmanuel Bernard]

I know that Max :)
I do not expose it to the user, it's just how HSearch internally deal  
with it during the transparent indexation process, so I do not break  
the == operation from a user point of view. Note that we expose that  
to the user anyway through load/initialize/get, I'm just begging for  
a facilitator.
Currently my code is fairly weak, since Steve can refactor anytime   
LazyInitializer using an AST parser and a maven POM approach,  
because... you know ;-)
I'm fine is we consider HibernateProxy and LazyInitializer as public  
APIs but it's not the case today, or at least I'm fine if we define  
an extended contract between Search and Core so that it won't break  
between micro versions.
