Problem:  In Vim9 script a line starting with a dict member is looked
    ahead at, to tell an assignment from an expression.  Where the
    expression runs on into the next line the lookahead cannot follow
    it, and what it makes of that reaches "v:errmsg" and whatever is
    being redirected, though nothing is wrong and the function compiles.
Solution: Turn error messages off around the lookahead instead of
    silencing them.

Thanks. I think we can drop the comment, I think it is quite obvious that emsg_off was meant to be used
