Possible to write a linter that knows type/comment information across packages?

[josebalius]

I want to write a linter that when it finds a composite literal definition for a struct, can look up where this struct was defined and whether any comments are attached to this struct. I can't find a way to do this with the current analysis flow of only executing one package at a time, it does not seem like comments are available under pass.TypesInfo. Has anyone done something like this?

Needed to use facts and record those comments to a type and then it makes it available.
