The module primordials proposal includes a Context constructor that
creates what is presently an ES execution context and contains its
intrinsic primordials.  The concept of a Context in that proposal is
completely orthogonal from the entity that manages the process of
grabbing module code (Load/Loader) or linking and instantiating them
(Require, which I've called a Sandbox in the past).  It's my
impression that the module statement in your proposal is a Registrar,
or a module transport declaration [1] that enables modules to be
transported in Programs.  I do not understand the Linking and
Instantiation semantics of the "Simple Modules" proposal, but it's
possible that the concerns of registration, linkage and instantiation
have been combined and additionally coupled to what I called the
context, in which case it would be appropriate to call the entire
entity a Context.  However, I think that for the purpose of this
discussion, it is desirable to separate the layers and concerns so
that we can see the breadth of options.
