Note that this patent indeed defines _declarative_ metadata annotations. That's the exact opposite of the imperative decorator proposal we are discussing right now, which completely conflates computation level and meta level and thus is pretty much unusable for compile-time hints. /Andreas > Or 'ambient decorators': > https://github.com/jonathandturner/brainstorming/blob/master/README.md#c6-ambient-decorators > > There's 2 patterns (maybe more?): > (a) Tagging a 'tree transformation' on a node. > (b) Metadata at compile time on a node. > > The thing about (b) is it can easily live outside of the code (like in > typescript where you have an optional header/declaration file) > > With (a), it seems more conservative to see how it gets used with classes > before bolting on to functions (opinion: end result in java is not something > to be proud of). > _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
