Please don't add "skip issue" to the title, it only makes it more work for us. We will apply the label in due course.

Okay, I'm so sory.

I don't think this is useful. We already say "return true", which usually implies that the opposite is "return false".

I do not understand why this comment is necessary, per the previous line, it always succeeds, therefore it returns an integer, which is a valid boolean value, it makes it redundant? Can you please elaborate as to why this is needed?

[F18-Maverick]

Yes, maybe your true, It's truely unnecessary. Sory about that, I'll close the PR soon.
