* @brief Instruction opcode values
*
* The instruction opcode table is divided in four parts. The high two bits of each
* opcode encodes the number of operands to pull from the codeobject and thus the
* size (generally) of the instruction (note that OP_CLOSURE(_LONG) has additional
* arguments depending on the function it points to).
*
* 0-operand opcodes are "simple" instructions that generally only deal with stack
* values and require no additional arguments.
*
* 1- and 3- operand opcodes are paired as 'short' and 'long'. While the VM does not
* currently depend on these instructions having the same values in the lower 6 bits,
* it is recommended that this property remain true.
*
* 2-operand opcodes are generally jump instructions.
