`${@:0}' expands to `$0 $1 ...', even though `$0' is not a positional parameter
The manual says:
>A positional parameter is a parameter denoted by one or more
>digits, other than the single digit 0.
And about `${@:offset:length}', this is what's written there:
>If parameter is @, the result is length positional
>parameters beginning at offset.
Given these statements, I wouldn't expect `$0' to be included in the
expansion of `${@:0}', yet it is.
Wouldn't it be better if it said
> ... beginning at offset, including $0 if offset is zero.
or something like that instead?

"If offset is 0, and the positional parameters are used,
$0 is prefixed to the list."

Yeah, I didn't see it first. Thanks
