A modern programming language that makes developers happier.

One small thing:

Say I have a custom abstract test spec class e.g.

```
abstract class FunctionNodeSpec(nodeType: String, body: suspend AbstractDescribeSpec.DescribeScope.() -&gt; Unit) :
    DescribeSpec() {
    // ...
}
```

Then inherit from that:

```
class ElementaryNodeTests : FunctionNodeSpec("Elementary node", {
    // ...
}
```

If I try to run an individual test case within `ElementaryNodeTests` I get this error:

```
Exception in thread "main" java.lang.RuntimeException: Could not detect spec class style for supertypes [class com.mycompany.testmaster.domain.nodes.FunctionNodeSpec]
```
