Description

For example:

import gleam/dict

type Grid(a) {
  Grid(Dict(#(Int, Int), a))
}

This is an error, since Dict is not imported. However, gleam/dict is. So we could either give a hint to import it unqualified: gleam/dict.{type Dict}, or (probably preferably), qualify it: dict.Dict(...) We could either just check for this in imported modules, or all importable modules.

Understand how the Gleam compiler resolves imports and types, then implement a suggestion in the error message when an unqualified type from an imported module is used.
