>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 4.0.2
>            Reporter: Christopher Smith
>            Assignee: Eric Milles

> This class works as expected:
> {code}
> class RoutingInfo {
>   String to
>   void hello() { this.to ?= 'alice' }
> }
> {code}
> Trying to use Elvis assignment from a class _in another file_ (it must be another file) causes the STC to lose track of the type of the RHS and complain that it can't assign Object to String:
> {code}
> class Other {
>   void world() {
>     new RoutingInfo().to ?= 'bob'
>   }
> }
> {code}
> {code}
> Groovy:[Static type checking] - Cannot assign value of type java.lang.Object to variable of type java.lang.String
> {code}
