✅ Safe type casting with LINQ?

As part of an octree I'm implementing, I have this line:

foreach (Leaf leaf in popped.Where(node => node is Leaf).Cast<Leaf>())

foreach (Leaf leaf in popped.Where(node => node is Leaf).Cast<Leaf>())

popped enumerates type Node. Type Leaf is a child class of Node. My question is, can I do this Where and Cast in a single operation which is type safe or does that line look correct as-is?

.OfType<>() maybe?

Yep, this is the answer.
