>             Project: Groovy

> {code}
> trait T {
>     abstract def foo(int i)
>     def bar(double j) {
>         println "bar $j"
>     }
> }
> interface F extends T {}
> F t = { println "closure $it" }
> t.foo(42) // `closure 42`
> t.bar(43) // `closure 43.0`; should be `bar 43.0`
> {code}
> Changing variable type to {{T}} works as expected.
