Good completion suggestions require extra type hints

[lassemaatta]

I was writing some Java-interop code with cider and noticed that I need to add a lot of explicit type-hints to get good quality autocomplete suggestions. It was suggested to me in slack that I ought to open an issue.

My assumption was that code like

(doto (BaseClass.)
  (.| ))

would provide completion for methods of BaseClass. Instead, it looks like I get suggestions for hundreds of methods from some other clases. For example:

To get better suggestions, I need to say:

(doto ^SomeClass (SomeClass.)
  (.| ))

Also, I noticed that the completions do not consider the class inheritance hierarchy. Here, the ChildClass inherits from BaseClass:

Thanks!

I'd say that the gist of this issue is similar to #111 , except that for constructors instead of static method calls.

We currently fail to type-infer for the simplest constructor call:

...The good news is that the improvement is definitely at hand.
