It is not really a metaphor more like a core OO concept.

But yes - it sounds weird for the C++/Java/C# crowd.

I think the Smalltalk/Object-C crowd find it much more natural.

It is a bit like relation/tuple/attribute vs table/row/field.
The first is the real relational concept, but in practice the
latter is much more used.
