Do targets need to be accessed lazily (i.e. configureEach) or is it ok to call targets.withType<T>()

[eygraber]

I ask because I'm running into the following issue:

kotlin {
  setUpMyTargets()

  targets.configureEach {
    if(this is KotlinNativeTarget) {
      if(konanTarget.family.isAppleFamily) {
        binaries.framework {
          export(project(":my-project"))
        }
      }
    }
  }

This leads to:

org.gradle.api.internal.AbstractMutationGuard$IllegalMutationException: Project#afterEvaluate(Action) on project ':engine' cannot be executed in the current context.
	at org.gradle.api.internal.AbstractMutationGuard.createIllegalStateException(AbstractMutationGuard.java:39)
	at org.gradle.api.internal.AbstractMutationGuard.assertMutationAllowed(AbstractMutationGuard.java:34)
	at org.gradle.api.internal.project.DefaultProject.assertMutatingMethodAllowed(DefaultProject.java:1444)
	at org.gradle.api.internal.project.DefaultProject.afterEvaluate(DefaultProject.java:1048)

Using withType doesn't result in an error

Entities like Targets, Compilations and SourceSets from Kotlin do not need to be configured lazily. Matter of fact: I would advise to configure them eagerly
