I'd probably expect $foo->new to clone $foo, but if the class author wanted that functionality they should have created an object method called "clone" or something like that.
That, I do not understand. If you expect the author to name clone functionality clone, then why assume that new clones the object?

I'd expect something called new to give me a new thing - not a cloned one.

Well, you can always use (ref $foo)->new if that's what you want.
That's not much of an argument, is it? With such an argument, we could do away with for/foreach, unless, and/or, q/qq/qw/qx, etc. There are always alternatives taking a few more keystrokes.

And note that the existance of ref $proto || $proto in a constructor doesn't prevent you from writing: 

    (ref $foo)->new

[download]
if 
    $foo->new

[download]
confuses you.

But the absense of ref $proto || $proto forces someone who doesn't confuse easily to write: 

    (ref $foo)->new

[download]
Ergo, using ref $proto || $proto gives the user of the module more choice.
