No, I was assigning a hash.
my(%h, %g, $x, $y, $z);
%h = ($x => $y . $z);
%g = %h;

There was no list on either side. Those are just hashes.
It's an "accident of the compiler's implementation" that
this turns into a list. It could detect this and do something
else.
my(%h, %g, $x, $y, $z);
%h = ("$x" => $y . $z);
%g = %h;

List assignment? What list assigment? This must be wrong.
my(@a, $x, $y, $z);
@a = ($x, $y . $z);

Huh? Why didn't this complaint? It's a list assignment!
Isn't it?
my(@a, $x, $y, $z);
@a = ("$x", "$y$z");

I ask you seriously: what it the *OPTIMAL* text you want to see here?
Let's pretend nothing is impossible. What do you REALLY want?
