Union Types

If Elm community is going to begin referring to "union types" instead of "algebraic data types" we should think about how that will work in practice. What discussions will we have? Will we find ourselves in awkward spots trying to explain things?

The following question/answer pairs simulate things I'd expect to see in a world of "union types". The pairs are grouped by what background I expect the questions to come from so we know the subtext. I have also added some meta comments in italic to explain my phrasing.

One thing to consider is that a lot of learners will not have a person to ask, so the path to arriving at these answers needs to be easy if you are just searching online.

Gradle Dependency Resolution

Normal Gradle behavior

The default behavior of Gradle to pick the newest version also applies if a lower version has been declared locally, but another dependency transitively pulls in a newer version. This is in contrast with Maven, where a locally declared version will always win.

For example, if your build.gradle specifies the dependency org.springframework:spring-tx:3.2.3.RELEASE, and another dependency declares 4.0.5.RELEASE as a transitive dependency, then 4.0.5.RELEASE will take precedence:

dependencies {
    compile("org.springframework.data:spring-data-hadoop:2.0.0.RELEASE")
    compile("org.springframework:spring-tx:3.2.3.RELEASE")

// will select org.springframework:spring-tx:4.0.5.RELEASE
