The story here is that vared is using the flag to the parameter that
indicates braces are present. They aren't, actually, it's just a trick
to get extra parameter effects to work. So the parameter code doesn't
care if there's extra stuff after the bits it's handled; the caller
needs to check. When setting the value, the parameter code needs to be
able to parse the entire expression and gives an error if it can't.
