[51b7345] | 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 type |
---|
| 9 | |
---|
| 10 | @max( int ) |
---|
| 11 | |
---|
| 12 | 3. constraining a type variable; the application is implicitly performed at the call site as in (2) |
---|
| 13 | |
---|
| 14 | forall( type 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 type |
---|
| 26 | |
---|
| 27 | (*attr_var)( int ) |
---|
| 28 | |
---|
| 29 | 3. a direct application to a type 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( type T | constraint( T ) ) int @attr( T ); |
