// I Compile-time resolution
// =========================
// 
// 1. an isolated name, where the argument is implicitly determined by the result context
// 
//    @max
// 
// 2. a direct application to a manifest otype
// 
//    @max( int )
// 
// 3. constraining a otype variable; the application is implicitly performed at the call site as in (2)
// 
//    forall( otype T | { T @max( T ); } ) T x( T t );
// 
// 
// II Run-time resolution
// ======================
// 
// 1. an indirect reference, where the argument is implicitly determined by the result context
// 
//    attr_var = &@max;
//    x = (*attr_var);
// 
// 2. an indirect application to a manifest otype
// 
//    (*attr_var)( int )
// 
// 3. a direct application to a otype variable
// 
//    @max( T )
// 
// Under what circumstances can this be done at compile/link time?
// 
// 
// III Declaration forms
// =====================
// 
// 1. monomorphic with implicit argument
// 
//    int @max;
// 
// 2. monomorphic with explicit argument
// 
//    int @max( int );
// 
// 3. polymorphic
// 
//    forall( otype T | constraint( T ) ) int @attr( T );
