Methods can return their results in one of two ways. The first, most robust, and most obvious way is for them to simply *return* the result. Sometimes, however, this option is not preferable. In this case, the method should take in a parameter called `into`, which should be a pointer of the "container" in which to put the result. For example, the method `ParsingOperation.parseEnumMembers()` takes in a pointer to an enum struct where the enum members need to go. As it parses each enum member, it adds it to the enum section's member slice. This approach is primarily for methods that parse *multiple* things, and in order to ensure good error handling, it is advisable to handle the parsing of individual items in a separate method.
