Resolution: Fixed
> STC: instanceof and for-in variable type
> ----------------------------------------
>
> Key: GROOVY-10179
> URL: https://issues.apache.org/jira/browse/GROOVY-10179
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.5.14, 3.0.8, 4.0.0-alpha-3
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 4.0.0-beta-1
>
>
> Variation of GROOVY-6240. Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test(args) {
> if (args instanceof Map) {
> for (e in args) {
> print "$e.key $e.value" // STC errors: No such property "key/value" for
> Object
> }
> }
> }
> test(a:1,b:2,c:3.14)
> {code}
> When the extra layer of the instanceof check is added, STC does not use Map
> type when inferring type of for-in variable "e".
