>             Project: Groovy
>          Issue Type: Improvement
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 5.0.0-alpha-1
>
>
> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test() {
>   def list_of_tuple2 = ['a','b'].withIndex()
>   print list_of_tuple2.collect{ s,i -> s+i }
> }
> test()
> {code}
> STC rejects this script, saying "Incorrect number of parameters. Expected 1 but found 2" or if "s,i" is "String s, int i" a type error.
> However it runs successfully without STC, printing "[a0, b1]"
