5Kotlin is probably going to be a bit of a wild west for a while, but please
6try to follow these guidelines as much as possible.
7
8 - No semi-colons: they are optional, we probably don't want them in the
9   future, so let's just not add them.
10 - No DSLs: sysui is complicated enough as is, let's not add more layers at
11   the moment.
12 - Only use extension functions for keeping complex code locality: Don't use
13   extension functions to add methods to android classes that you always wished
14   were there, instead add them directly to the class and save us the extension.
15 - inline, reified, and de-compisition can all be great things: just make sure
16   you know what they do and why you are using them.
