/*

example of building a bytecode handler table.

My full implementation here:
https://github.com/rwy0717/intbuilder/blob/master/intbuilder/include/BytecodeHandlerTable.hpp

The difference:
  In the example, the handlers all take a single arg: the bytecode builder.
  In the real implementation, the handler's take their VM state as a second argument.
