[Feature request] Show procedure type hint on returned values

[BigBoyBarney]

Hi!

I'm not sure how feasible this is, so feel free to close this issue if it isn't.

I've run into cases a few times, where a procedure returns a bunch of things, and I have to go to go back and forth to get the type hint, since it's only shown when the cursor is on the procedure itself.

Example:

_, _, _, _ := map_entry(&some_map, key)
^^^^^^^^^^
If the user is editing this part, no type hint can be shown

Would be lovely.
Thank you for all your work!

Cheers!
