Really? Wow. I had no idea, and I really tried to sound non-condescending.

I simply don't agree that redundant casts are something to be ignored, since they can be harmful and hide actual errors (the cast is a bit like `sudo make me a sandwich`, it makes the compiler do what you say which is not always a good idea).

I guess I believe that publicly posting code, and even writing a compiler for the language in question, kind of automatically marks you as interested in the language and open for ideas of usage and so on.

My apologies to the OP if you were offended. Thanks for the feedback, @gizmo.

FWIW, I liked your suggestion, the author’s explanation, And your follow on written understanding.

If someone’s technical article is submitted and they are themselves participating in a discussion out feeling insulted, then accusations of unsolicited advice are unfounded.

I didn't find your tone condescending at all, it was a perfectly fine comment (esp with sources)
