• Determines which opcodes are valid in each epoch, and also has a 'read-only' mode for byzantium:
  • https://github.com/ethereum/go-ethereum/blob/master/core/vm/interpreter.go
• Just objects with opcodes:

## [It would be nice to import a library, another contract's interface, or a 
## parent to inherit from]
## but that's not supported. Yes, inheritance is dangerous, but code reuse can 
## be very beneficial as
## well. I believe adoption will be held back by this. 

## [Declare a positive number] Why change the type from `uint256`? `num` is 
## less descriptive, ie. it could include irrational numbers for all I know. 
## Also, will 4-byte identifiers be compatible with solidity? 
## ie. `bytes4(keccak256('uint256'))` or `bytes4(keccak256('num'))` ? Or is

Fun little learning exercise, what's the shortest bytecode you can send that will publish a contract with non-zero bytecode? The response to getCode() should have some characters that aren’t either 0 or x.

To test it out:
