Thanks @KostyaTretyak! Gonna flag this for milestone 0.5.0. If you could take a look at #1002 - I believe it could cause this to have merge conflicts in the future as we would need to add tests to document and validate the solution works. Cheers.

@joshbruce no, it does not seem that my changes were in conflict with the changes introduced in #1002.

shouldn't this be 'simpleRule' + i ?

[KostyaTretyak]

Yes, you are right, I'll correct it right now. Thank you.

See #1026

Closing as merge conflicts - also building out the issue above to consolidate ideas and approaches proposed.
