Missing Dict import when using Elm.Annotation.dict

[adamdicarlo0]

The Elm.Annotation.dict function does not, on its own, cause Dict to get imported. I saw this when adding a feature to elm-open-api-cli (permalink that requires clicking 'Load diff' on SchemaUtils.elm).

This rears its head when nothing else in the File calls a Dict function, which is exactly the case when elm-open-api-cli generates an OpenAPI schema's Types.elm module.

SSCCE repository is here, but here's the code that generates a bad module, for reference:

import Elm.Annotation as Type

fileMissingImport : Elm.File
fileMissingImport =
    Elm.file [ "MissingImport" ]
        [ Elm.alias "SomeDict" (Type.dict Type.string Type.int)
        ]

The code it generates:

module MissingImport exposing (..)


type alias SomeDict =
    Dict.Dict String Int
