* declarations where an instance of the template should be considered, for

* MOZ_IGNORE_INITIALIZATION: Applies to class member declarations. Occasionally
* there are class members that are not initialized in the constructor, but logic
* elsewhere in the class ensures they are initialized prior to use. Using this

* in constructors via list-initialization, in the constructor body, or via functions

* MOZ_NON_AUTOABLE: Applies to class declarations. Makes it a compile time error to
* use `auto` in place of this type in variable declarations. This is intended to
