String concatenation in the assert messages has drastic impact on test
runtime. Removal of these messages is unlikely to affect debugging if
any breaking changes are made.

lgtm, nice find, can you speed up MOAR TESTS? |

I feel like assert messages should probably just be code comments in most cases. If you see it, it's because bad stuff happened. If bad stuff happened, you are going to look at the code. If you look at the code, you are going to see the comments that explain why it was making that assertion. |

LGTM and what @Qard said makes sense. |
