Shadow-Devil opened a new pull request, #1785:
URL: https://github.com/apache/groovy/pull/1785
Consider the following:
```
@groovy.transform.TypeChecked
void test(int[] ints) {
ints.eachWithIndex { value, index ->
println "$index: ${value.doubleValue()}"
}
}
test(0,1,2,3,4,5)
Compiler reports "[Static type checking] - Cannot find matching method
java.lang.Object#doubleValue()"
```
`eachWithIndex` is only provided for reference types, so "value" is seen as
Object by the type checker.
Currently, only a draft for int arrays. Should probably also be implemented
for other primitive types.
There are three different approaches to do this:
1. Copy-paste the implementation for each overload
2. Delegate to `eachWithIndex(Iterable<T> self, Closure closure)`
3. Delegate to `eachWithIndex(Iterator<T> self, Closure closure)`
I found option three most appealing since option 1 adds unnecessary code
duplication and option 2 just calls option 3 with the iterator of `self` which
would add unnecessary overhead.
