v0.3.0

This is a major change to Lucy introducing 2 major changes:

Invoke is now callable

Using invoke now requires you call it like a function.

state start {
  invoke(thing) {

  }
}

Otherwise it is unchanged.

Symbols

Symbols are explained in the docs. In short they provide a mechanism for references something that needs to be passed in on the JavaScript side, such as a guard function. The syntax for symbols is a : followed by a name, similar to how they are used in Ruby and Elixir.

state idle {
  pay => guard(:hasFunds) => processing
}
