In this case, documentation is essential because:. This is also the origin I am pretty sure of the "don't repeat what you are doing in the comments.

There's a separate Specifier, BlueprintReadOnly , that you can use if you want the property to be treated as const in Blueprints. I do not go back over written code and try to come up with the comments then. What you write depends on your audience. Studies have shown that this is easier for beginning programmers.
