Description
Go to definition is a useful feature. However, it works only for project's code. I would love to be able to go to definition for code that belongs to dependencies (either it is for the base or any other dependency that is used in the project).
Example usage
I have code in my project that uses the function max from base. When I try to go to defintion of the max function, I get the the right code file where it is defined. Next, I can go to other definitions even in that file etc.
Example from other ecosystem
One example where I'm aware of this feature is Dart programming language (Flutter), it has all the code files downloaded in the project's directory (gitignored). It downloads all these code files once pub get command is run (pub can be understood as cabal in haskell world. pub get is also run automatically when build happens etc.).
And when trying to go to definition, it goes to the correct line to one of the relevant downloaded files present at the project's directory.
I'm curious whether there is some ongoing work that could help achieving this feature. Not sure whether this is relevant to this project, but I believe that you could point me to the right issues/projects in case it's not.
