> When Groovy applies a trait to class it erases parameter name data. You can see this here:
> https://github.com/apache/groovy/blob/982bd38b3216ea3143b0d667d2cd47d2c758f884/src/main/java/org/codehaus/groovy/transform/trait/TraitComposer.java#L157
> So regardless whether `-parameters` is specified to the compiler traits will not retain parameter name information.
