Use type name instead of the !type value in code completion

Question

I have a function which has a resultData parameter with the type of DataView. This looks like the following in the code completion tooltip.

...resultData: fn(buffer: +ArrayBuffer, byteOffset?: number, byteLength?: number)...

My preffered code completion would be:

...resultData: DataView... 

Is that somehow managable?

Answer 1

After reaching out one of the Tern.js developers he answered the following:

"Not really. Tern doesn't use type names when showing function types, because those would usually be unhelpful."
