It is associated to the definition or declaration, through the owner() member, 
and can be retrieved from the declaration/definition through 
internalContext().

That the context doesn't have the identifier assigned makes the thing a little 
harder to overview, but isn't problematic since you anyway don't need to 
address content of a compound-statement globally in C++. This is the way it 
was when I started working on that stuff, so I've kept it. Maybe assigning 
the identifier to all contexts that belong to a function would be better for 
overview, that's the only use of those context-identifiers anyway, as long as 
you don't need to address members from outside.
