Hmm, I'll keep this in mind in case things start getting start 
getting more out of hand. Thanks! :)

Mixin strings are still kind of like black magic to me, so I 
prefer not to use them unless I really think they would help a 
lot. In this case, I only do this 3 times in the entire codebase, 
so it's not worth it yet.

And Dennis, sadly that wouldn't work for me since `version = XYZ` 
only affects the current module and I'm using this check in 
multiple modules.

Thanks for the help!
