Caution: these might not play well with kotlin-native (see https://github.com/JetBrains/kotlin-native/tree/master/samples).

I have a few questions here @shyiko.

1. Could you elaborate a little on why these rules might not play well with Kotlin Native?
2. Is the current direction to make all of these name checks into a single rule, or would it be better that these are distinct rules?
3. Would you consider adding a rule for constant values being UPPER_SNAKE_CASE?

Any updates on that? @shyiko @iggymoran @jzbrooks

The current naming rule conventions seem quite clear and unambiguous. Some simple rules can be extracted quite simply from those conventions.
