Interacting with the system

[WWRS]

Proposed: pop "a","b": push "a" and write "b" to a file named "a" pop "a" or [a]: push subprocess.call(a)

These would allow the original challenge to be done in Actually.

Also consider: pop "a" or [a]: push subprocess.check_output(a) 41 (A): if stack is empty, push "Actually" 53 (S): if stack is empty, push "Seriously"
