Is your feature request related to a problem? Please describe.
It is possible to create an infinite loop; this will cause the program to hang.

Describe the solution you'd like
Past states should be stored (probably in a set), and then if the exact same state is encountered again execution should terminate with an error.

Describe alternatives you've considered
I honestly can't think of any good ones.
