Array assignments to a list of scalars raise exceptions on mismatches

[snoopyjc]

Array assignments to a list of scalars raise exceptions on mismatches. In perl they silently copy over as many elements as they can and fill in the rest with undef if need be. Mimic this behavior in the generated code. For example:

my @arr = ('a', 'b', 'c');
($thing1, $thing2) = @arr;   # copy over the first 2 things
($t1, $t2, $t3, $t4) = @arr;   # copy over the 3 elements - $t4 is undef
