Nit: Maybe we want to make this as non-doxygen style comment because this comment is not specifically tied to a code but just a note?

Just curious @brianhou @jslee02, can you implement something like the following to make that explicit boolean cast work? (See Update section) |

This PR follows the blog post above. I think the biggest annoyance with this implementation is that there's no contextual conversion to
bool, so you can't write something likeif (mOptions & Options::POSITIONS). My intermediate workaround is to requireOptions::NONE = 0and compare directly to that.I'm not entirely convinced whether this complication is worth it. @jslee02, what do you think?
