As a programmer, I have a base interpreter on which to build and prototype.

Example: [ “forward”, “turn-left”, “forward”, “turn-left”, “forward”, “turn-left”, “forward” ]
Interpreter/vm:

A program counter
A set of pluggable “action handlers”
A step operation that executes the current action and increments the program counter
