Distinguish types of calls for call hierarchy?

For the call hierarchy, @rbuckton brought up that JavaScript and TypeScript has many different ways of actually invoking a function:

• New new Foo()
• Tagged templates: foo`bar`
• Decorators @foo
• Property/Element access to accessors obj.foo

My proposal is that TS should return call hierarchy items for all of these cases, but I wanted to check this with you @jrieken. Does that make sense? Should we consider having a way to distinguish different call types?

Possibly, I’ll see what I can come up with.

I don’t have any specific use cases in mind, but I’ve seen similar features in other tools (such as Reflector) respect this kind of classification. For accessors especially, it can be useful to distinguish between call sites using the setter and call sites using the getter. Many hierarchy items will only have a single classification (classes can only be new-ed, most functions will only be called, etc.).
