TLA+ vs FizzBee
FizzBee is a multi-paradigm formal language. It supports a number of paradigms, including functional, procedural, and actor model. Folks familiar with TLA+ will find the functional style familiar and tend to make every action atomic. With that approach, FizzBee might appear to be just a syntactic sugar even though it is much more.
In this page, we will see the benefits of not exclusively relying on defining every action as atomic.
