Result is "Is Null? true".
Is this the correct behaviour? I would expect compiler to point
to an address in the heap, but set the length as 0. So, it
wouldn't return null,

While writing max ulong value, I added the "u" postfix. So
compiler accepted it as ulong value (That's my interpretation if
correct on compiler's side).
writeln( 18_446_744_073_709_551_615u );
But when I try to print out minimum value of long, compiler says
Error: signed integer overflow
Maybe I am just too stressed out to see the problem.
