Paul King updated GROOVY-7447:
------------------------------
    Description: 
As a follow-on from GROOVY-4787, the following code:
{code}
@groovy.transform.ToString
class Person { String name; int age }

@groovy.transform.TypeChecked
def myMethod() {
        assert Person[ name:'Dave', age:32 ].toString() == 'Person(Dave, 32)'

        def timMap = [ name:'Tim', age:49 ]
        assert Person[ *:timMap ].toString() == 'Person(Tim, 49)'

        assert Person[ *:[ name:'John', age:29 ] ].toString() == 'Person(John, 29)'

        def ppl = [ [ name:'Tim', age:49 ], [ name:'Dave', age:32 ], [ name:'Steve', age:18 ] ]
        assert ppl.collect { Person [ *:it ] }*.age == [49, 32, 18]
}
myMethod()
{code}
fails compilation with the following errors"
