    That's because you used literals, so the range operator is expanded at compile time. If you used 
    my $max = 2e7;
my @aa = 1 .. $max;
my @bb = 1 .. $max;

    You'd get no error, as the lists are expanded at runtime and immediately thrown away.

      Thanks!! your replies perfectly answer my question. I can't still believe perl list assignment has the flaw/bug like this though. I will use list assignment at runtime at most.

        I am not understanding why memory exhaustion would be a considered a bug or flaw.
