> Cloned from the @EqualsAndHashCode issue to handle the same problem with @ToString as an independent issue.
> I have the following class representing a location in Amazon S3. Depending on some inner business logic, I often need to split the object key into a prefix and a file name, so I access them all through the {{getKey()}} method; with S3, the only thing that matters is the final concatenated string.
> The generated {{toString}} method doesn't display properties following the JavaBean conventions, e.g. with explicit getXxx() or isYyy() methods but no field as per normal Groovy conventions for properties with auto getters/setters.
> {code}
> import groovy.transform.*
> @ToString(includes = ['bucket', 'key'], includeNames = true)
> class S3ImageLocation {
>     final String bucket
>     final String prefix
>     final String subKey
>     S3ImageLocation(String bucket, String prefix, String subKey) {
>         this.bucket = bucket
>         this.prefix = prefix
>         this.subKey = subKey
>     }
>     S3ImageLocation(String bucket, String subKey) {
>         this(bucket, null, subKey)
>     }
>     String getKey() { prefix ? "$prefix/$subKey" : subKey }
> }
> // expected below (current is 'S3ImageLocation(bucket:foo)')
> assert new S3ImageLocation('foo', 'bar', 'baz').toString() == 'S3ImageLocation(bucket:foo, key:bar/baz)'
> {code}
