Is there any reason to expose an internal collection as a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection?

Bu tür senaryolarda, IStructuralEquatable arabirimi sebebiyle koleksiyonların yapısını ve yürekğini düz bir şekilde karşıtlaştırarak uygulama başarımını fazlalıkrabilir ve muta manipülasyon işlemlemlerini güvenilen bir şekilde gerçekleştirebilirsiniz.
