When playing around with the overload module, I found that perl parses 
$x | $y | $z

[download]
as if it were 
$z | ($x | $y)

[download]
I was hoping to a new (left-associative) operation on a new data type (objects of a certain class), so that I could write: 
$x | $y | $z

[download]
and have it translate to: 
f(f($x,$y),$z)

[download]
where the order of the arguments to f matters, but it doesn't look like I can do that with overloading.
