// NOTE: Currently Global only refers to CTX::MID and Message only refers to
// CTX::GMSG and CTX::MID through the GMSG parameter. It would seem that we
// could use those two types as parameters directly, without needing a full
// context. The only problem is that when dealing with a concrete
// implementation of a session::Context, referring to these associated types
// must be "disambiguated" with the syntax:
//
//     Message <
//       <Mycontext as session::Context>::MID,
//       <Mycontext as session::Context>::GMSG> ... ,
//
// which is must more verbose than simply:
//
//     Message <Mycontext>

/// Unique ID for each global message type used in a given session context.
