This feels like a _very_ peripheral aspect of style to attempt to standardize. It's not mentioned in the GitHub ruby style guide, for instance. On the other hand, that style guide (and another I looked at) seem to implicitly encourage no newlines after opening a class or module. And I can understand the desire to make the codebase as consistent as possible.

In short, I'll try to change my ways :sunglasses: 

We should look into getting RuboCop to flag violations, though. Trust, but verify.
