-----------------------------------------
paulk-asert commented on PR #1785:
URL: https://github.com/apache/groovy/pull/1785#issuecomment-1255602797
We have used code generators (hand-hacked throwaway Groovy scripts) from
time to time to generate repeated patterns.
We could enhance both the dynamic and static behaviours to do some kind of
array-level "auto-unboxing" for T[] and the like but we have opted not to in
the past for better Java integration and (at the time) efficiency with the
hand-coded primitive variants likely to be more efficient.
We also have `IntArrayIterable` (and Long/Double variants). So we could
write:
```
public static int[] eachWithIndex(int[] self,
@ClosureParams(value=FromString.class, options="Integer,Integer") Closure
closure) {
eachWithIndex(new IntArrayIterable(self), closure);
return self;
}
```
This saves work when writing the new variants but is probably slightly less
efficient that the current code in this PR.

> Project: Groovy
> Issue Type: Improvement
> Components: groovy-jdk
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Minor
>
> Consider the following:
> {code:groovy}
> @groovy.transform.TypeChecked
> void test(int[] ints) {
> ints.eachWithIndex { value, index ->
> println "$index: ${value.doubleValue()}"
> }
> }
> test(0,1,2,3,4,5)
> {code}
> 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.
