Let me try once more. I want that fn() to act like
sub fn { my @a = (3,5,7); return @a}
You are letting the scalar context of the caller to bleed through the return
and effect the _syntatic_ meaning of the comma.

Not the same. I'm only interested in action-at-a-distance. Where there
is a sub and a return in between. I have no objection to that.

To you perhaps. I feel that the syntactical change is unexpected.
But do you any objectsions to making this limited change? When the
EXPR of a return is a literal list, it should not have its comma
changed?
Will my proposal bleed into anything else in the language?
