>                 URL: https://issues.apache.org/jira/browse/GROOVY-10816
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 4.0.6
>            Reporter: Robert Elliot
>            Priority: Minor
>              Labels: named-parameters

> The following code fails to compile:
> {code:groovy}
> import groovy.transform.NamedVariant
> trait Foo {
>   @NamedVariant
>   def foo(String username = "sdf", String email = "ghj") {}
> }
> {code}
> with this error:
> {{Groovyc: Error during @NamedVariant processing. Class Foo$Trait$Helper already has a named-arg method of type [org.codehaus.groovy.ast.Parameter@15247533[name: namedArgs, type: java.util.Map, hasDefaultValue: false]]}}
> It works fine as a class.
> It fails as an interface with a default method.
> Perhaps this is intended, but if so I failed to find any documentation specifying that {{@NamedVariant}} only works with classes.
