[jira] [Created] (GROOVY-10029) SC: produce direct method call for for collection to array assignment

Eric Milles created GROOVY-10029:
------------------------------------

             Summary: SC: produce direct method call for for collection to array assignment
                 Key: GROOVY-10029
                 URL: https://issues.apache.org/jira/browse/GROOVY-10029
             Project: Groovy
          Issue Type: Bug
          Components: Static compilation
            Reporter: Eric Milles
            Assignee: Eric Milles


Consider the following:
{code:groovy}
@groovy.transform.CompileStatic
void test() {
  def list = [1, 2, 3, 4]
  Number[] array = list
  println array
}
test()
{code}

Groovy supports the implicit conversion "array = list" under STC/SC as of GROOVY-10002 and GROOVY-8983.  Can the static compilation mode replace the call to {{ScriptBytecodeAdapter#castToType}} with a direct call to the collection's {{toArray()}} or {{toArray(T[])}} or the extension method {{toArray(Class)}}?
