[Feature request] create class without builder with internal constructor

[RingerJK]

/**
 * Represents a person.
 * @property name The full name.
 * @property nickname The nickname.
 * @property age The age.
 */
@DataCompatInternal
private data class PersonData(val name: String, val nickname: String? = null, val age: Int)

/**
 * Represents a person.
 * @property name The full name.
 * @property nickname The nickname.
 * @property age The age.
 */
public class Person internal constructor(
  public val name: String,
  public val nickname: String?,
  public val age: Int
) {
  public override fun toString() = // toString

  public override fun equals(other: Any?): Boolean = // equals

  public override fun hashCode(): Int = // hashCode
}

It can be used for classes that are public, but mustn't be created outside of a module
