TypeScript symbols is empty inside closure (like jQuery plugins)

I tried developing basic jQuery plugin with TS, looks like the symbols list is totally empty if I use following code:

/// <reference path="./typings/tsd.d.ts" />
(function ($: JQueryStatic) {

    interface Anything {
        something : string
    }

    function func() {
    }

})(jQuery);

I think it should recgonize the whole file spanning closure and not let it ruin the symbols listing.

I also think this is annoying. Symbols view only shows symbols in the global scope, also for Javasript. If you use class expressions for Angular, like .controller('MyController', class MyController { ... }) you will never get any methods of that class show up in the symbol view.

much needed feature.

This is an issue with TypeScript. For JavaScript this actually works a lot better then for TypeScript despite using the same language service...

@billti had a fix for the JS case. we need to unify the two implementations. #7523 tracks some of this work.

@andy-ms would this be handled by your refactor?

In the #8958 branch, Anything shows up, but func doesn't. We had decided that inner functions wouldn't show up if they didn't have any children. I don't know how exactly we should handle this, but maybe the entire module going in a single closure is a pattern we could recognize — although trying to recognize particular patterns like this could pile up to a list of messy special cases.
So, not sure if this is totally resolved. Improved, though.

i think that is a better place to be in. if that turned out to be another source of complains, may be we should allow all function declarations regardless if they are containers or not.
