# Because the idea of what one instruction does, does not always map one to one to real machine
# instructions, and instruction may link to another instruction thus creating an arbitrary list
# to get the job (the original instruciton) done
# Admittately it would be simpler just to create the (abstract) instructions and let the machine
# encode them into what-ever is neccessary, but this approach leaves more possibility to
# optimize the actual instruction stream (not just the crystal instruction stream). Makes sense?
# We have basic classes (literally) of instructions
# - Memory
# - Stack
# - Logic
# - Math
# - Control/Compare
# - Move
# - Call
# Instruction derives from Code, for the assembly api
class Instruction < Code
# Make hash attributes to object attributes

@attributes = options
