Looks to me like with a few appropriate methods, you have left-to-right

(@foo, @bar) := @a

    . part [/foo/, /bar/];

Hmm. Does operator precedence allow that?

@a . grep { $_ > 0 } . sort { $^b <=> $^b };

Or does it think the second dot is attempting to call a method of the thing returned by the closure { $_ > 0 }, not the result of (@a.grep { $_ > 0 })?

E.G. if 'grep' is a normal method, wouldn't the dot operator bind more tightly to the closure { $_ > 0 } than the method name 'grep' would?
