Just chatted with @whmii about this. I am thinking it's best to keep using all `-`'s just to avoid casually inventing a new naming syntax. BEM is really a means to an end, which is strong (unique) selector names. So, as long as they are strong, hyphens will do just fine.

**Riff Warning**
Everyone hates the double dash and double underscore in BEM. Are there any other characters we can use? The only requirements for a strong selector naming system are to enable:

* multi-word nouns and adjectives (`-` in BEM)
* modifiers (`--` in BEM)
* implied descendants (`__` in BEM)
