Annotation & Attributes & Reflection

[hagb4rd]

Annotations in JS would definitely make it golden. Is there a perspective? are some of for the necessary reflection methods in scope of the spec-staging groups? .. or would you say those could be applicable by some some v8 extensions?

Decorators (which are dynamic, but allow static analysis for some forms) are coming, but they're still draft proposals:

See:

• https://github.com/wycats/javascript-decorators/blob/master/README.md
• https://docs.google.com/document/d/1ikxIP5-RVYq6d_f8lAvf3pKC00W78ueyp-xIZ6q67uU/edit#heading=h.t9k9f05noi8w

For the time being, the Babel comment plugin is probably the best way of using this, but it's also not finished yet: https://github.com/origamitower/metamagical/tree/master/babel-plugin
