The phantom polymorphic variant qualifying AST nodes is reversed: - previously, we were explicitely restricting each AST node to the passes where it belonged using a closed type (e.g. `[< dcalc | lcalc]`) - now, each node instead declares the "feature" it provides using an open type (e.g. `[> 'Exceptions ]`) - then the AST for a specific pass limits the features it allows with a closed type The result is that you can mix and match all features if you wish, even if the result is not a valid AST for any given pass. More interestingly, it's now easier to write a function that works on different ASTs at once (it's the inferred default if you don't write a type restriction). The opportunity was also taken to simplify the encoding of the operators, which don't need a second type parameter anymore. |
