From the grammar, I would not assume GP is a native english speaker, much less monolingual.

It seemed perfectly cromulent to me.

I would love to hear what exactly about the grammar doesn't sound native.

The only thing that seems strange is “such commands as” used to describe a single command. I think a more common way of writing it would be “a command like.” But, I don’t think it is at all definitive, it could just be a native English speaker who went with a slightly odd phrasing.

I guess that my pun using "unreal" in a post about a game engine went under the radar and now I look like I can only speak English which is kinda flattering and worrying.
