I've spent some time with di.js [0], and it actually allows a few different ways of handling injection, one of which is simple type annotation, i.e.: class Foo { constructor(bar: Bar, baz: Baz) { ... } } There's also syntax for using @Inject annotations inline in the constructor to provide more flexibility. The architecture may be coming together, but it sounds like there's still a long way to go before it's a fully-realized framework with more friendly conventions. If anything, I think the upshot is that DOM handling has been pushed further to the edges, and the emphasis is on pure composition of classes and data structures, with less boilerplate, hand-waving, and framework-centricity.
