The lobby provides access to the major Namespaces, which are objects suitable for organizing things (for now, they are essentially just Cloneable objects). The most important one is prototypes, which contains the major kinds of shared behavior used by the system. Objects there may be cloned and used directly, but they should not themselves be manipulated without some design effort, since these are global resources, having a name-path identifier which can be freely shared. prototypes is inherited by the lobby, so it is not necessary to use the namespace path to identify, for example, Collection or Boolean. However, without explicitly mentioning the path, adding slots will use the lobby or the local context by default.
The prototypes namespace further contains inherited namespaces for, by example, collections, and can be otherwise enhanced to divide up the system into manageable pieces.
