| paulb@22 | 24 | |
| paulb@22 | 25 | The docstring annotations have the following meanings: |
| paulb@22 | 26 | |
| paulb@22 | 27 | NAME Indicates a "stable" name used by callers of a function |
| paulb@22 | 28 | instead of a generated name which would distinguish |
| paulb@22 | 29 | different specialisations. |
| paulb@22 | 30 | |
| paulb@22 | 31 | NATIVE Means that the class or function body details are not |
| paulb@22 | 32 | accurate representations of the actual code and should not |
| paulb@22 | 33 | be generated by a compiler. |
| paulb@22 | 34 | |
| paulb@22 | 35 | INTERCHANGEABLE Indicates that instances of a class are not sufficiently or |
| paulb@22 | 36 | meaningfully distinguishable from each other with regard to |
| paulb@22 | 37 | instantiation. |
| paulb@22 | 38 | |
| paulb@22 | 39 | SPECIAL Indicates that the compiler should try and optimise calls to |
| paulb@22 | 40 | the annotated function. |
| paulb@22 | 41 | |
| paulb@22 | 42 | ATOMIC Indicates that the class and its instance(s) cannot store |
| paulb@22 | 43 | attributes, although some may be predefined (such as the |
| paulb@22 | 44 | __true__ method). |
