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

while (($a,$b) = somefunc()) { ... }

If it used the number of elements on the left, it would always be true.


>>>It counts them. :-)
