Review comment:
I'm pretty sure the problem is with this line here. The return type is
supposed to be ARRAY<BIGINT>, but the type returned here is
ARRAY<ARRAY<BIGINT>>. I'm guessing it's because `x.getOperandType(0)` is an
array type. Instead it should be the type of elements inside
`x.getOperandType(0)`. (I'm not sure exactly what the method is to get that,
but you should be able to figure it out using the debugger.)
