style guide

[ylixir]

document style things

• include const definitions for static functions
• snake case for functional code
• camel case for oop code
• functional code should be static functions with no state, or invokeable classes with no state, or anonymous functions
  • specifically not allowed are namespaced functions
• everything should be in alphabetical order: includes, functions, array keys, etc
• rename test providers to make them alphabetized
• objects should never mutate
• corollary to no mutation is that constructors are always private/protected
