Subject: [PATCH] Allow NamedLoaderContexts to be returned from loader

It is useful in some cases to return NamedLoaderContexts from loaded
functions. Instead of choking or requireing implimenters to call the
context's value() method before being de-scoped, detect when a
NamedLoaderContext has been returned and return the value from the
current context.
