1// I Compile-time resolution
2// =========================
3//
4// 1. an isolated name, where the argument is implicitly determined by the result context
5//
6//    @max
7//
8// 2. a direct application to a manifest otype
9//
10//    @max( int )
11//
12// 3. constraining a otype variable; the application is implicitly performed at the call site as in (2)
13//
14//    forall( otype T | { T @max( T ); } ) T x( T t );
15//
16//
17// II Run-time resolution
18// ======================
19//
20// 1. an indirect reference, where the argument is implicitly determined by the result context
21//
22//    attr_var = &@max;
23//    x = (*attr_var);
24//
25// 2. an indirect application to a manifest otype
26//
27//    (*attr_var)( int )
28//
29// 3. a direct application to a otype variable
30//
31//    @max( T )
32//
33// Under what circumstances can this be done at compile/link time?
34//
35//
36// III Declaration forms
37// =====================
38//
39// 1. monomorphic with implicit argument
40//
41//    int @max;
42//
43// 2. monomorphic with explicit argument
44//
45//    int @max( int );
46//
47// 3. polymorphic
48//
49//    forall( otype T | constraint( T ) ) int @attr( T );
