Minor change from 5.0.0 to 5.1.1 causes compilation errors if aliasing List.Extra as List

[joeandaverde]

import List.Extra as List

My elm-package.json has these dependencies:

"elm-community/list-extra": "4.0.0 <= v < 5.0.0",
"elm-lang/core": "5.0.0 <= v < 6.0.0",

Error is:

-- NAMING ERROR - ././src/REDACTED_FILE_NAME_HERE.elm

This usage of variable `List.singleton` is ambiguous.

REDACTED LINE OF CODE 

Maybe you want one of the following?

    List.Extra.singleton
    List.singleton

This failed because we imported a module aliased with the same name as a core module. I imagine others will break for a similar reason. This type of import seems to be used commonly in many examples.

I think the problem is that list-extra and core didn't both get a major version upgrade.

List-Extra did a major version change whereas core did a minor version change. This discrepancy caused elm-package to download one update and not the other.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

In order for us to proceed with a build I believe the best course of action would be to specify exact versions.

@joeandaverde elm-lang/elm-package#259 seems to make this fix impossible. Requires a code change to recover.

Upgrading to list-extra 6.0.0 should resolve this issue.

Wouldn't that mean all of my dependencies that depend on List.Extra would have to upgrade to the latest version also?
