This won't pass the static analysis :).

Maybe<T> contains an `alignas(T)` member, and thus isn't safe to pass by parameter, due to ABI not being required to respect alignas(T) fields. Right now it is marked as MOZ_NON_PARAM, and once bug 1339537 lands it will also be rejected due to the alignas member. (See bug 1287006 comment 26 for a more detailed explanation).

Try passing these fields by const reference instead :).

Again, pass by const reference here.

Gah.  I wish we'd just run that on try automatically instead of it being a separate platform.  :(

Thanks for catching this!

mmm, copy/paste.  Fixed.
