The following is from page 75 in the Camel:
List assignment in scalar context returns the number of elements produced by the expression on the right side of the assignment:
$x = ( ($a, $b) = (7,7,7) ); #set $x to 3, not 2
...why?"
>>>Because then you can use it for a boolean value:
while (($a,$b) = somefunc()) { ... }
If it used the number of elements on the left, it would always be true.
"...how.?"
>>>It counts them. :-)
