IEnumerableをそのまま使うと、使う度に毎回変換される。遅延実行。 http://confluence.jetbrains.com/display/ReSharper/Possible+multiple+enumeration+of+IEnumerable

Assuming that GetNames() returns an IEnumerable, we are, effectively, doing extra work by enumerating this collection twice in the two foreach statements. If GetNames() results in a database query, you end up doing that query twice, while both times getting the same data.

ということで、特に複数回使う場合など適宜ToList()やToArray()しておく。

1. StartCoroutine(MyCoroutine()) is like MyCoroutine()

Until the first yield return X,
StartCoroutine(MyCoroutine()) is exactly like a regular function call MyCoroutine().

MyCoroutine is like
