Design goals

ideas

• functional programming is cool!
• message passing is key to reliable/resilient systems.
• event driven design is necessary for natural domain modeling.
• DDD is a great design guideline.
• state machines are building blocks of distributed systems.

to achieve

• Expressive domain modeling
• Test driven development and general testing must be as easy as validating against literal numbers
• serve as a CQRS chassis
• we should be able to run a specific program with different interpreters with different characteristics.

non goals

• general tools for all the scenarios
  this library is designed specifically for event-driven/event-sourced applications with a DDD mindset in mind, it would be suitable for those specific problems, and probably a bad fit for others.
  
• performance
  while it is considered as much as possible, to eliminate unnecessary works and do works as efficient as possible; performance has lower priority than being expressive. if you know how improve specific performance problems I would be very happy to discuss the matter, or more happy if you do a PR!
